The 680s are amazing yes!..
but, I cant accept the 2gb Vram limitation, and yes I say limitation.
yeah I know "2gb is fine and dandy cause no current games ever use more than 1.9gb at 1080p etc etc etc" ...
BUT, 2gb is not enough for future proof reassurance honestly, games are almost maxing out the 2gb limit as is, and give it 2 years, maybe even 1 year, and they'll well breach those 2gbs.
and not to mention SLI future proofing,
I mean if you wanna plug in 2 or even 3 extra 680 into your system down the road sometime for that extra power, well shame, cause this 2gb is gonna bottleneck the sheep out of any game released in the future, and a lot of that extra processing power from 2way, 3way, and especially 4 way SLI will go to waste.
anyway

The reason for this long winded comment it to vent some of my frustration while I wait for the 4gb cards to be released.
And that's when the 680 will really be amazing!
