Not really. Being CPU bound isn't typically a binary situation -- either CPU bound or not CPU bound. As different frames may produce different levels of stresses on various subsystems, you certainly can't say that something is or isn't "CPU bound" just because all cards at a certain level of performance aren't showing precisely the same average frame rates. That's a very unrealistic way to view the data.Plus, if it was CPU bound, the GTX and GTS would be at the same fps, not stacked in Tiers.
We can reasonably assume that significant bottlenecking is occurring if the typical performance spread between platforms narrows significantly. If the spread is practically non-existent, then we can infer that there's a severe bottleneck.
I'm really surprised at your level of apprehension about coming to the same realization as everyone else is about this. Most of us are looking at the GT's specs and calling its position among other cards a "no-brainer".
Of course. Most tend to severely overemphasize the need for a blazing-fast proc to keep frame rates up. You're at a disadvantage, yeah, but you're still going to get good performance on that platform.would this card run good on an x2 4200+ AMD oc'd to 2.8ghz Socket 939 ?
