what's up everyone James two cents here and before we jump into today's topic I want to remind you all that I am currently doing a giveaway of one of my GT X 1080 founders edition cards one of my very own cards that was intended to go in skunk works before when I'm going to tighten X's it is a worldwide giveaway you guys will find the link to the giveaway down in the description of the video and I'm not only giving away the card I'm also giving away a full cover plexi nickel ek water block as well as a Nickelback plate for it so yeah you definitely don't wanna miss out on that is available worldwide except we're prohibited but the topic of today's video is definitely guaranteed to ruffle some feathers upset some people and that perfectly okay with me because we are going to talk about five pc myths that you shouldn't believe hey guys illness the overwatch Coolermaster invitational on July 15th and 16th at eSports arena in Santa Ana the tournament gives 12 high school robotics teams a chance to compete for a grand prize of forty thousand dollars directly benefiting their school's robotics program so save the date and come on out to the eSports arena in Santa Ana on July 15th and 16th now the first myth here is kind of a two-parter and it basically says you can't build a PC on carpet that kind of ties into the whole anti-static or ESD electrostatic discharge argument which is if you accidentally shock something in your system you can damage it now that's very true but there's a lot of things that have changed over the years a lot of components these days have very good ESD protection a lot of motherboards specifically now have ESD caps on they're designed to absorb any ESD that might accidentally make its way into the system and I'll tell you right now almost every PC you've seen built on this challenge just about every PC I've ever built in the history building pcs I've done while sitting on carpet and the argument with carpet is the fact that it can build up static chart if you've ever walked across the carpet with socks on and touched a doorknob you know exactly what I'm talking about so the fear is that you would accidentally shock something on your system and kill it now that doesn't mean that even though we have ESD protection today that you can't damage your component so that's why I say it's somewhat true but you could damage some of these smaller components in your system for instance HDMI ports USB ports you thunderbolt type-c ports these types of things if you get a charge that accidentally makes it directly into the port that could cause damage I do know people who have killed ports that way but you've never actually destroyed the system that's we've come a long way in ESD protection now this next one's a good one I hear it a lot amongst people who are sending me build lists or asking me questions and that specifically is can an oversized power supply damage your computer well the problem is a lot of people who don't really understand power supplies and electricity and how these components work together is they tend to think that if your computer only needs 500 watts to run under load but you hook up a thousand watt power supply that you're sending a thousand watts to your computer I've seen a lot of comments saying using an oversized power supply can damage your system and that just boggles my mind the way a power supply works is it's only going to supply the amount of power that the computer needs up to its max rating so a thousand watt power supply can supply up to a thousand watts of power to the components that doesn't mean it's sending a thousand watts at all times now the reason why you'll see people use oversized power supplies and me being one of them is I want to kind of try and size the power supply to be more in the peak of the efficiency curve right around 50 percent is where 50 percent usage or load is where a power supply is most efficient so a thousand watt power supply supplying power to a 500 watt system would be at the height of its efficiency curve but of course there's going to be a huge diminishing return in terms of cost where you're going to spend a lot more 4000 watt power supply then say a good 650 or 700 watt power supply which could also maintain that same sort of efficiency curve so you want to pay attention to diminishing returns and not go too big the only thing you're really going to destroy when you use a power supply it's too big is your wallet now this next one is a pretty popular myth and you've probably seen it if you've ever been to any Co a PC forum Facebook group or even a comment section in my videos and that is you can speed up the slow computer by adding more RAM or technically downloading more ram as some people call it anyway I digress guys that really depends on why your system is running slow in the first place do you have an extremely undersized or underperforming CPU based on the tasks you're asking of it are you talking about gaining performance and you have a very slow GPU well things like that Ram is not going to actually help where Ram is going to help is if you have tasks that are utilizing a huge amount of data being stored in the memory CAD drawings video rendering or huge Photoshop projects that stuff is heavily RAM dependent because all of those previews and stuff are stored in memory and what happens when you run out of memory is your computer doesn't just shut down people seem to think if you have too little memory and you asked more of your memory than it has capable that your systems is going to blue screen or shut down that's not true what happens is it starts to access what's called a page file in the Windows environment or a swap file in the Linux environment where that data is then stored on the hard drive or even an SSD the problem is even n dot two SSDs are extremely slow compared to the data rates and transfer speeds of the physical memory itself so if you're starting to have to share data and swap files with your hard drive that's what's going to slow down your PC so most gaming PC's home pcs or home PC environment are not going to be doing things that need more than roughly sixteen gigabytes of memory but having faster memory and more memory is of course going to have a diminishing return just like power supplies so it really comes down to what you're doing with your PC now this is one I've actually heard quite a bit considering the fact that I used to work in IT in an enterprise environment was this is a good one to talk about and that being gaming PC's make terrible workstation pcs and and that I don't entirely understand now let's we're talking like full-on CAD rendering pcs with multi CPU Z on systems with 128 gigs of ECC registered Ram or whatever you're building servers then this doesn't really make a whole lot of sense because I don't know about you most gaming enthusiasts tend to go quite overboard with their hardware more than often than not they build pcs that are way above and beyond what they need to play their games because they're enthusiasts and they like high-grade Hardware at least most people here if you can't afford it you would use it if you could you know what I'm saying so I don't understand how people can say gaming pcs are not good workstation pcs oftentimes they have at least 16 gigabytes of RAM or more they tend to have multi-threaded CPUs usually it's some sort of i7 with hyper threading or now arise then with all these cores which would make a great workstation PC and now with GPUs being used in a lot of day-to-day tasks and a lot of programs able to offload on to GPU encoding it makes more sense and ever a gaming PC is really a dual-purpose PC you can work on it and you can game on it and no longer do you have to have a specific build guide or direction based on that use case you can now have a gaming PC that you can also build an entire business based off of now this next one I know it's one that we have all heard guaranteed if you've ever read any discussion on any website or a youtube comment or anything regarding GPUs and GPU performance and high refresh rate monitors its who cares the human eye can only see blah blah blah FPS anyway and you can replace blah blah blah with any denomination because nobody can agree on what the human eye can actually see now I can tell you there was a really good discussion that took place on reddit yeah I know right I read a reddit post very strange a good general consensus at least amongst eye experts was that the human eyes and the nerves can fire anywhere between 300 to a thousand times per second sending information to the brain and that information travels at 200 miles per hour for me I - your brain I don't know how to measure that but whatever again I'm not no I'm McCollum optometrist but I can tell you that most people in here actually agree that the human eye can see approximately one one thousandth of a second now how that actually translates to FPS I don't know but what I can tell you is that what we can definitely see is the variation between frame rates yeah TV is only at what 29.97 FPS movies are at 24 p or 24 frames per second and the reason why that looks super smooth is because of two things one extremely consistent frame intervals the frame is being rerender dinh redrawn exactly the same amount of time between each frames so that gives you a lot of smoothness the second thing is when you're dealing with video cameras and stuff like that there's a lot of motion blur so you get blurred images between those frames which makes it like that's what we're doing right now this is this is looking super smooth at 30fps because of the fact that the frames are blending together in games it's not like that is a very harsh redrawing frame over and over and over and over there's no blending between the two so of course it added things like motion blur to games try and give it that cinematic effect that most of us turn that off anyway but the problem is if you're getting 60fps and then 75 and then 58 and then 62 and 70 one that's a constant change of frame rates where you're getting different gaps between frames as things adjusting what's happening on-screen so that's why you have now frame pacing a technology like free sync and gsync and v6 of course been around for quite a while where the point is to draw the frames consistently there is no conclusive argument to this and that's certainly not going to happen today because the problem is all of our eyes are different all our brains work at different speeds again read the youtube comment so that will make sense to you not everyone's brain fires at the same time not everyone's eyes are transmitting the same speed of information and not everyone's eyes are created equal so of course it's a very subjective subject matter subjective subject matter if that yeah you know what I'm trying to say guys go with fast GPUs go with high refresh rate monitors and enjoy it I promise you will see a difference and if you say you can't why refer back to the the brain firings beeping so anyway I had basically asked you guys on Twitter last night tell me your top PC myths and maybe would make it into a video and basically what I did was I took the ones that seem to be reoccurring a lot of people were mentioning over and over and those are the ones that made it in here maybe we'll do another installment of it we talked about five more PC myths you shouldn't believe here's another myth you shouldn't believe and that's the fact that Jay is a PC fanboy Lane doesn't like Mac well you
