Right, there is no point discussing this any further as we are never going to agree
I am well aware that if you want to apply loads of AA, play at a res higher than 1200, SLI/crossfire, 3D or whatever then 2GB is diff beneficial.
HOWEVER at a res of 1200/1080 it isn't unless you have slightly less powerful cards like the 560TI and I am sure the 6870 would also benefit if you could get 2GB models, but when it comes to the more powerful cards as I have said and IMO, there is going to be very little difference in FPS and is not worth sacrificing a 1280MB GPU e.g. the 560TI 448 for a 560TI 2GB, as I have seen some people recommending here in the last few months instead of the more powerful/better card......
Also a 580 1GB would still kick every other cards ass IMO.
Thank god, the next gen cards will all be 2GB+, no more arguing/discussing about 1GB VS 2GB for 1080
