Yes. the Seasonic x750 is a very high quality, high effeciency PSU. Its even listed as a certified SLI PSU for 570s. Also, the new generation of Nvidia GPUs (the 670s) use a bit less power so youd be fine there as well.
There are actually reports the x650 will run SLI 570s, but its likely pushing it.
The 850W will allow more headroom though. But you may not need it unless running higher power draw GPUs than a 570.
Now for 580s, you might be getting close to its limits.
But SLI 570s will pull around 650-750 watts from the wall in game at the high end.
Lets say your pulling 750W, the PSU will be about 88% efficient or so.
So that means, if pulling 750W from the wall, at only 85% effeciency, you only using arounf 630W from the PSU. Well within its range.
And thats a bit exaggerated. realistically, you'll only be pulling 650-700 at most from the wall.
They are also capable of delivering more than the rated power for a time. Though I wouldn't want to let it do that for any length of time, or avoid it if possible.
Now, if you run Furmark and Prime95 at the same time to stress the system, you may have issues. But bear in mind, No app or game will ever come anywhere close to that type of power draw.
--On the SSD
I know many have thier own opinions and thats fine, no one is wrong is what they prefer.
But personally, I prefer a 80GB SSd for the OS and Apps only. Pagefile, Temp, all programs (except games) go here.
I use a dedicated spinner for most games, and for games that Im currently playing or have high disk use, I have a secondary SSD thats dedicated to games as well.
A 2nd spinner for User DATA and Media.
And finally a 3rd Spinner for Backups only.
I prefer to keep games off of my OS SSD, as it makes System Images/restores faster and easier.
But thats just my way of doing it. I know some do prefer one large SSD, rather than 2.
