Haven't decided whether I want to go with an HD 4870 or a GTX 260 (factory overclock @ 650 mhz) but I do know that I want a power supply capable of running either of those in crossfire or sli. I've heard that 600 W with a good 12V rail is enough for crossfire but the 260's consume more power at load. I was thinking of getting the Corsair 750TX:

I want a good power supply but I'd rather not spend more than $100. Will that be enough?

That's a good PSU, but I prefer the PC Power & Cooling S75QB 750W.

Another vote for PC&POWERCOOLING 750W,however if u have lots of HDDs and want to OC alot then i say u may want to look @ a 1kw power.

It is possible to run on that little power, but if you push your ps hard like that it will degrade fairly quickly and then the power it supplies won't be enough. The corsair is cheap(ish) and reliable, and has enough of a power cushion to keep your system powered for a long time.
