Seeking advice for graphics card upgrade

[nycguy]

Hello everyone.

After a few months of playing Starcraft 2 with no problems, my computer now randomly shuts down when playing the game. I've lowered the game graphics settings, done numerous virus scans and driver uninstalls and reinstalls but the problem was not fixed so I assumed it was a hardware problem.

Here are my computer stats

NVIDIA GeForce GT 120
Vista 64
Intel(R) Core(TM)2 Quad CPU Q8200 @ 2.33GHz, 2336 Mhz, 4 Core(s), 4 Logical Processor(s)
RAM 8.00 GB
PSU Corsair GS600

I changed my PSU when the problem first started from my original 400W PSU to the 600W one listed above.

I am going to upgrade to a better graphics card that will hopefully fix my Starcraft 2 problem, but I also would like to start playing CoD Black Ops.

I have a bunch of store credit at gamestop so if possible I'd like to use one of their cards, these are the ones they have available.

Galaxy GeForce GT220 1GB DDR2 625MHz $69.99

Galaxy GeForce GTX460 1GB GC $189.99

Galaxy GeForce GTX470 GC $299.99

Any help in this matter is greatly appreciated.

Thank you,
Ryan

Your monitor resolution????
BTW GTX460 Should be enough for those 2 games at any resolution.
