I mean this in the politest way possible: even a year and half ago the 3200+ was outdated..
as for the 8600GTS, don't believe what NVIDIA tells you on the box, the 8600GTS is a straight up POS, and DX10 is a load of BS.. for the same money (or even cheaper), you could've gotten an older, but much better performing X1950PRO, or even an HD3850/70, an 8800GT or even an 8800GTS G92 if you wanted to spend a little more.
Consult these here forums more often for good advice.
and Good luck sorting your system out. Crysis is a great game, but it's the bleeding edge in visuals, and so you'll need the bleeding edge in hardware to run it with maxed settings, and even then it'll not be 100% smooth.
