I was wondering if the following is possible: to piece together a machine that includes a GeForce 8600GTS and is under $600? The pieces needed are: motherboard, CPU, RAM, case, power supply, and the 8600GTS. No hardware needs to be specific for overclocking as the computer will be run at stock speeds. Ideally, there would be 2 GB of RAM. Any suggestions on the different components is greatly appreciated. Thanks!
