Other games behave similarly. I also force triple buffering with Riva Tuner. How much more could I get with a GTX 280 or 285?

Just being able to adjust voltage to stabilize clocks helps these 65 nm cards render at the same level of the higher cards. I really don't think that you'll see all that much of an improvement on the higher level cards as compared to the 260's. With this voltage tuner, EVGA just extended the life of the 65nm 260's.
Damn your GTX 260 has a high stock voltage mine was 1,06V,also I doubt most people will see 800 core on their GTX260
