I'm interested in building a new computer because the computer I'm using right now is 5-6yrs old. I'm thinking about getting the 7900gs video card with AMD Athlon 64 X2 4800+ Brisbane 2.5GHz, I would get the c2d but I don't know how to overclock so I'll just play it safe with the amd x2. My budget is around $500-$600. Can anyone please recommend me a decent motherboard to go with it?
