I will be building another computer in the next few months and I'm looking at motherboards right now. I think ill go with AMD so I want a socket A, has to have 8x AGP, dual channel DDR. I don't need any audio features cause I already have a good soundcard. I would use it mainly for gaming. I want the computer to run Doom 3 decently. Looking to pay around $150. What other feature should I look for? Thanks.
