Sorry, I should have been more specific. This is not a gaming computer. Web browsing, office documents, Java programming, etc. I am not planning on spending more than $70-$100 on the GPU. Here are the other products I am using.
Case: COOLER MASTER RC-690-KKN1-GP $79.99
Power Supply: Thermaltake Purepower W0100RU $34.99
Hard Drives: Intel X25-V $114.99
SAMSUNG F3 HD502HJ $54.99
Memory: CORSAIR XMS3 $154.99
Video Card: MSI N9600GT-MD1G $94.99
OS Microsoft Windows 7 $109.99
Software Microsoft Office Home & Student $59.99
Optical Drive HP Black 22X $26.99
That comes to $730 so I have $150 - $200 to spend on the CPU and around $100 for the motherboard.
