Video playback is a cinch, with technically perfect scores. Still, it’s the same as all current video playback, which is to say, there are still moiré issues.

I was taken aback by how much air this heatsink moves through it. While there are passive variants of this card, they’re rare and a bit costlier. If you’re looking for silence, I think you’re best served by digging up an older HD 3850. On top of it, the fan speeds picked up quite a bit when things got renderin’ hard. But this card doesn’t run hot at all, and could do well with some RivaTuner tweaking, particularly since the card uses so little power. This card came in at 25W idle and 40W load, which is an amount of power I haven’t seen capable cards consume for a couple of years. That’s a good thing, I mean; most current hardware really pegs the PSU, and this is a happy exception.

Overclocking was particularly limited, unfortunately, gaining only 40MHz on the core and memory both, or a little less than six percent overall. If this card were a little more ambitious, it’d be easier to recommend.
