This really is a strange product.
Surely a 4850 1GB version is a more interesting market offering. A "cheaper" 4870. (apologies if this product is already out there). To "cripple" (its all relative) a GPU to 512 then turbo boost it with 2 GPUs?? That's like a rocket strapped to a go-cart. My guess is it will WHIZZ until it needs to do some texture swapping with main memory, which may be frequent due to only 512MB "effective" GPU space, then suffer from those nasty microstutters/frame lags as graphics assets are loaded and swapped in and out of the GPU.
Actually, on EDIT, I take that back. IF you are gaming at "popular" resultions like 1680x1050 or 1600x1200 you are probably absolutely fine. You get extra ZOOM with the x2 processors.
BUT, if you are running high-res like 1920x1200 or 2560x1600 then you might suffer from the limited memory issue.
SO, net net, this is a great performance part for a "consumer" gamer, but NOT a good part for a workstation or "elitist" gamer.
