[Hardware Question] SSD just for the OS?

[Codex]

Go SSD for sure. If you can afford it, get a 120GB to use for OS and games. Win7 rocks on SSD.

As for socket 1366, I wouldn't go down that path. Bang for buck you're better off with 1156, as the only difference you will notice will be in SLI / Crossfire bandwidth, and that will only become apparent if you're going to use 3 or more cards.

I don't know what SoW will ultimately be like on my 2 cards at 1920x1200 but I'm confident it will be more than enough.
