Up to $150,
Only run 1-GeForce 9500GT ( to play FPS games)
Don't OC, just run them out-of-the box.
This is my second (ASUS P5N-E), first one lost its ability to use external USB ports.
Second one got fried by a leaking cooling system (took a 8800GTX with it).
Have the original one back in, a couple of week ago lost RAID plugs.
