Aghhhh, I don't know which one to pick. A lower tier card with higher VRAM. Or the higher tier card with lower VRAM.

OR

They're both roughly the same price so I don't really care about price, I just want to know about performance. I'll be playing on a 1080P monitor.

Here's the rest of my build:

570 really struggles to find a case where it can use a larger frame buffer at playable frame rates and once you restrict the settings to keep things within playable frame rates the 4gb buffer isn't an issue.

It is really more the graphics cores and how it is aging on the 570 then VRAM limit.

You also eat into your power budget by another 20w-40w so boost clocks tend to be a little lower and thermals higher a little higher on the larger buffered models.

Oh hey Gilroar, thanks for your wonderous advice again, I'll stay with the 580 then.

I would like to know how my build has been doing today after a few weeks ago. Yeah, this thread was pretty much the same as the last one you've commented on but I'm sticking with the RX580 ASUS DUAL4GB for now instead of the XFX like you've recommended me to.

Not bad at all.
