ATI's universal decoder shines here, and does much better than NVIDIA's previous generation, and for the nitpicker, does a better job handling moire than the HD 3850 (although the scores do not reflect this within HQVs scoring scheme).

And here's where all the not-quite-there performance makes up for it. For the casual enthusiast (oh that shouldn't make sense) who is more concerned with energy performance than high-def gaming, this is a card to beat. I mean, yes, it idles a little higher than a 3850, but even that's not by much. At under 50 loaded watts, I'm even somewhat surprised that the heatsink isn't passive. The fan, with the drivers I have, couldn't be tweaked. It's not good, but it's not annoying. You might mistake it for an over-zealous CPU fan, and thankfully, you will be able to tweak it down the road, that much Sapphire has confirmed for me. Which would be great, since the card doesn't get over 60 degrees and doesn't need that much cooling, anyway. In the meanwhile, the fan's speed doesn't vary, the pitch doesn't shift, and it's not really distracting, something I wish other 4000-series cards would take to heart.

I was able to overclock the memory a clean 140MHz, or 14%; this serves to add much-needed memory bandwidth, and helps close the gap between it and the other cards well. The core, on the other hand, only overclocked 28MHz, more, or just three percent. This is either a fluke or a bad sign. It's certainly not the cooling, which is more than adequate.
