This is just something that i've been wondering since i saw the results of the HD 5870's performance in w1z's review here. Like the graphs' show the HD 5870 only ever outperforms the HD 4870x2 at 1024x768, which doesn't really matter since no one in their right mind that games at that res would purchase such a card. But i thought i'd heard a couple or few times somewhere that ATI might have trouble getting all their shaders utilized n that they had some trouble with utilizing even the 800 shaders on the HD 4890/70/50. Now i don't own any HD 58XX series card(yet), but I had thought that since the HD 5870 has all 1600 shaders on a single die and double the ROP's that the HD 5870 would outperform the HD 4870x2 by a decent margin esp once AA was enabled but it doesn't. Am i the only person that thinks this? I know we can expect at least 10% more performance with mature drivers, probly up to 20%, but i'm still curious if what i'd read a few times is or could be true with ATI having a difficult time managing all 1600 shaders.
