@Raven_Sword: There is no need for a 750watt psu in this build. You are clearly not the enthousiast "FILL THE ENTIRE CASE WITH LASERBEAMSLICROSSFIREGRENADES!" guy. 620 would be fine, even if you later decide to put another GTX560 in there.
A SSD is awesome, but you have to consider the low amount of storage. I don't know you, but I know that 120gb would never be enough for me. Consider getting another harddrive to compliment your SSD.
Also, Im curious: why the 560ti? I can personally recommend an amd 6950 (2gb), if you can find one for a similar price.
