EVGA GTS250 SuperClocked vs. Palit GTX 260

I'm relatively certain the GTX 260 is better bang for the buck. It will probably use a little more power, but that's what you get with a better card. The temperatures I am not sure about, I guess the 250 runs a bit cooler but that's also something that goes along with a lesser powered card. The only thing about that GTX 260 is the brand; eVGA definitely has a better reputation and "extras" (e.g. step-up program) in comparison to Palit.

EVGA is a much better brand but the 260 is a much more powerful card. The 260 needs a 500w power supply with 36a on the 12v rail/rails. The 250 will draw slightly less.
