For 1, good luck fitting an OS on a 32GB Drive.
For me, Vista alone takes up over 20GB. Couple that with AppData, your Desktop and Documents, Restore points, the page file (if you don't move it off the SSD), temporary files, etc., stuff really fills up quick more than you think and you may find yourself running out of space. SSDs also should be kept under 2/3 full for best life/performance. For me, I have nothing on my SSD but the OS, MS Office, and Firefox, and I'm struggling to keep it under 45GB on my 60GB Drive.
Second, you would see nearly identical real world performance at a much lower price if you went for an Athlon II X4.
Last, and some people may disagree, but as much as I love NVIDIA, I've been pretty disappointed with their 4xx Generation and I would recommend an ATI Radeon unless you've got a really good deal on the GTX460. A 5830 is about on par with the GTX 460. But get a 5850 if you can, it has a much better price/performance ratio.
