Can you fit this one into your budget? It's just a little bit more expensive, but it will power your system well.

No, wattage ratings are meaningless if you don't look at the rest of the claim. For instance, is the 600 watt peak or sustained? Is it at real world temperatures or taken in an unrealistic freezer? There are 500 watt power supplies out there that can easily outperform some "700 watt" power supplies. There simply isn't the regulation to keep the claims on a level playing field. Audio is in the same situation. Ever seen a $10 500 watt amplifier that weighs like 1 lb?

I'd be happy running SLi GTX 275s on a 650W power supply. The only trouble is that most of them don't have enough power connectors, except the TP-650.

all i have to say is dont be afraid to spend a little more on the power supply when thinking ahead like if our gonna SLI/Crossfire down the road. cause im looking for the same thing, a GOOD Power supply that will last me a few years...i just dont have any money....

well its important that you have enough on your 12v rail just a little tip

Depends on the power supply. On a REALLY high quality unit, I most definitely wouldn't have any issues with that either (depending on the rest of the rig). However, multi-rail or lower amp unit, I would most definitely not.
Like with your PSU, I would not recommend running 2 275's with that. While sure it'll run it, and could possibly do so for quite some time. However, it'll be running most of the time at a much higher load therefore becoming more inefficient, and you'd wind up actually using more power than if you just had used a bigger PSU.
Not to mention, it could also affect your overclock due to power surges within the system when certain peripherals are engaged and increased ripple (poor input signal). Aside from that some motherboards manufacturers recommend a minimum of 400w just for the board itself.
All in all you're better served by getting a larger PSU. It'll run cooler, more efficiently and provide a "cleaner" input signal.
