If you want some fun look up benchmarks for the AMD HD 6670, it may be what the PS4/Xbox 720 are based on.
Really weak ass card, really hope the rumors aren't true.

Yeah, nVidia to have much more wiggle room for a 6 series card on a larger bus, . I'm fine with 2GB of memory, I don't run games at mad crazy resolutions which would require >2GB, I'm a 1080p guy.
Way I look at it,the 680 at the same clock is going toe to toe with the 7970 on a smaller memory bus. :O
It's wrong to suggest nVidia have over clocked their cards 10%. These are shockingly cool cards. Never get over 50 c. Not like my old 9800GTs which would go straight to 70 just by looking at them.
