GPU advice needed

[Rhodan]

I have the following system:

Intel Pentium Dual Core E2200 2.2GHz
Asus P5GC-MX
2GB RAM

Currently it's using the onboard Intel gfx, and I was thinking of upgrading it with a decent GPU so I can play some games on it.

I would appreciate some advice on what would be a good GPU choice for this system, considering that it's not exactly high spec and there would be bottlenecks so I don't want to go overboard with the GPU.

Keep in mind I have a Viewsonic 17" LCD which is 1280x1024, so the resolution won't be going higher than that for the games.

I'd like to play the following games with good eye candy levels and frame rate:

Far Cry 2
Crysis Warhead
Fallout 3
Stalker Clear Sky
Dead Space

Thanks

many games dont depend on cpu too much, however cpu is more important on lower resolutions

Thanks for the reply.

I also have an iMac which has an ATI HD 2600, would the cards you suggested offer much better performance than what the iMac is capable of?

One other thing, the PC only has a 350 watt PSU, would this be OK for these kind of GPU's?
