Rx 580 4gb or Rx 570 8 gb

Hi, i was wondering if it is a better idea to go for an Rx 580 that has 4 gb or instead a Rx 570 that has 8 gb. I saw one of LInus' video where he said that not having enough Vram can make the games unplayable and that's probably the only reason why I'm still hesitant. I know that currently the 580 will give me better performance but I'm thinking a bit further and wondering if 4 gb will be enough in a few years and if the 570 will not be better in the future just because it has 2 times more ram.

 

So what is your suggestion ? Better GPU with less Vram of slightly worse GPU that has more Vram ?

Are those your only 2 options? If you live in the US, an 8GB 580 is only about $10 more than a 4GB.

I live in Canada and currently there is a nice deal on the 580 4gb and the price dropped even bellow the 570's price. I want to build my first PC and don't have a big budget so I want to spend arround 250$ (canadian) on my GPU.

Well, it's a bit tricky because plenty of games use over 4GB of VRAM these days, however some say a RX 570 isn't graphically powerful enough to utilize 8GB of VRAM but I do not know if that would hold true for all games or not.   I do not have a RX 570 so cannot comment directly on that.    I do have a RX 590 here and playing Black OPS 4 I'm usually sitting at 6.7GB of VRAM used.   So the 4GB is going to hold back the 580 a bit but is more powerful.

You should be able to buy an RX580 8G new, within your budget.  Currently there are 6 different RX580 8G on Newegg under $200 USD.  Not sure if their pricing is the same up in Canada, but with the conversion rate, that's pretty close to being in your budget.  

 

Since it's your first build, post your pcpartpicker list and have some people double check it for you.  A balanced build is important to the overall performance of your system, and a lot of times first time builders will over spend in certain spots and under spend in others. 

 

If the above mentioned cards are out of your price range, given that an RX580 is essentially a boosted RX480, you could probably overclock the 480 8G to a core speed relatively close to an RX580.  Also, the cooling solution matters.  If the 580 is a blower style, or founders edition card.  (the ones with a black shroud over it and one little red fan) and the 480 is the style with two bigger fans on it, then I'd go with the 480 for sure.
