That is just not true. First off, bf3 scales the LOD based on VRAM and the 580 was the fastest card for bf3 for a long while despite larger VRAM cards being available (ie 6970)In BF3 with ultra and msaa kills the 580s fps. I think the 79xx series is perfect with 3gb vram
At 1920x1080 on ultra with 4x msaa bf3 uses 1586mb of vram
I've said this a million times but view the presentation at last years geforce LAN where a DICE developer was present - the VRAM usage scales back and becomes more efficient with less VRAM available. View it. I know i've stated this a billion times.
Lastly, this entire argument is freaking stupid because it won't happen. Customers should have a choice just like they had a choice with the GTX 580, a 350$ 7970 1.5gb would sell very well...On that note, I find it pretty humerous that the GTX 580 1.5gb was just fine when the 7970 was released but apparently now (per toyota) you NEED 3GB. What? Anyway, AMD doesn't have business sense to give customers a choice of a more cost efficient card, instead they get 3gb overkill which is worthless for anything less than 3d surround. Even for 3d surround, 2gb is fine unless you're playing crysis 2 or skyrim with tons of mods. Anyway - And THESE type of arguments are like arguing with a stop sign....just watch. But..AGAIN...MOOT DISCUSSION cuz it isn't happening. So might as well just drop it eh? Arguing about something that will never ever happen. Stop sign.
