I am upgrading a system I built back in 2006. I am willing to spend $75 for the CPU and $75 for the GPU. The computer will be used for simple everyday tasks. The only gaming that will be done on it will be Counter-Strike 1.6 and the new Counter-Strike: GO once it comes out. No Photoshop or video encoding type stuff will be done on the computer. I've narrowed it down to three dual-core CPUs. One AMD and two Intels.

And the video card I've chosen..
EVGA GeForce GT 430 (Fermi)

What do you think? Currently the PC has a 3200+ Venice and 7600GS, so I should get a nice performance upgrade with these lower end parts.
