yes you can set affinity, i do, but i have come to the realization that it works about as good as a a P4 with hyper threading(C2D), and is as good as a P4 in multitasking! my 4400 is much better multitasking and setting affinity... And i concur on the 3gz..? As for the "feeling", well i think it has to do with the mem controller( lack of,C2D) and DDR2. Back on topic, a phys card would be great if cost and effects are worth it..duh, I dont see devs doing much codeing for cpu effects like you will get with Ageias...?What? I'm not following you here? You can assign each core a different task using Task Manager by setting the affinity. But in a game you're not going to be able to tell which core to run what unless the game is designed for that. I think you're opinion on Conroe might be a little odd, I can't see how someone spending as much as you did on a processor feeling great about it either...
I also don't think the above effect would take much more than your typical A64 X2 or C2D though, saying "3Ghz" is really pointless and I don't think it would need that much power. As said earlier Alan Wake and Crysis have similar effect and Crysis at least is designed to run on a slower system than a 3Gz C2D.
