but this looks like a fantastic card. Its a shame they didn't compare the GTX 650 (GDDR5 bandwith in particular) but if HD 4000 doesn't do it for you, this will.
The only (slight) issue is with colour spaces, RGB range and all that. Drivers should fix that though. For those interested in pushing MadVR right up, this will do it.
Looking forward to my next build when Haswell is released.
