The GTX260 216 is mid-level? Noooo...it's just an aging king of the hill.
See if this works:
That's a ranking. Where's the 5830 in that list? Bottom. It's not suppose to run with nVidia's 260's. It's a progression of SKU'd parts, and these are what didn't make it to be bigger GPU's. We've been doing this for decades folks. "my q9300 cpu isn't an x3350". Duh?
And graphic cards aren't made to fold. We hate cuda out here, but love it in folding...different worlds. That's not ATI's fault, that's Stanford's issue they need to deal with.
Chumly, I think your missing the point here. Its more than just the fact in 1(ONE) game it loses to a GTX260 at multiple resolutions. In several games, even tho has 320 more shaders,same ROPs at a higher clock speed and more bandwidth, it loses even to a 4870 a few times and a 4890 several times. The card, even "IF" it is the lower end SKU of the highend line, it still shouldn't be losing benches to slower old cards in DX10 games.
