My GTX 560 Ti deal is over. There is no stellar GPU buy right now.

This should also further solidify the importance of buying a PSU at a good deal.
Here's a comparison of the two:

The major difference is price: the seasonic was $120, the corsair is $141-$20=$121.
The efficiency on the seasonic is 1% better, and fully modular.
Both will power whatever you want just fine, do it equally as well, and you won't notice any difference at all between the two ever.
In reality, you don't need anything over 650 W (and you could get away with 450 W). For that reason, if you can make your computer $700, get all high efficiency parts, you can get something like this and bet sitting pretty on an extra $70 from saving on the PSU. Note that even this PSU is not a good deal, since the 550W capstone used to be $64.

7950 computer uses 300 W at the wall. "The Radeon HD 7950 leads the way, with an idle system power consumption just over 93 W (that’s a Core i7-3960X-powered platform with 16 GB running at 4.2 GHz, remember)"
Add in 150W for good measure, since average power consumption is usually around 66% of MAX power consumption, consider that you're buying a good PSU that can handle more than its rated wattage for short periods of time, you're good.
Please note that if you can afford GTX 670, get it. It's much more efficient than the 7950, and 10% faster.
