I'd go with at least 4gb vram for future proofing, so 570.
I had an 660 SLI setup where I had plenty of performance but no VRAM (2gb) and that sucked big time when new games got released.
All depends on what you like in games though, I'm a sucker for textures haha
I was having the same issue in decision making. And barring no sudden releases or fluctuations I decided 570 for the VRAM
I'm keeping an eye out on Amazon Warehouse though for a discounted 1060 6GB
Awesome thanks, basically just looking for a card that will run games, I dont care about textures, I play everything on very low and when my current rig struggles with that, time to upgrade so future proofing is a nice thing.
Now to wait for the 570 to come back in stock
