So I have $600 and want to get a reasonably decent gaming machine, however I have no previous experience with building PCs. I already have 2 hard drives. an 80gb SATA 7200rpm and some other I don't remember (it's upstairs in the room I'm using if it's really that important). I also already have all the peripherals I need, keyboard, mouse, monitor, and a cd drive. I could use a good dvd drive if there's one that's reasonably cheap.
I've already weighed the advantages for a video card and so far I'm going with a GeForce 8600GT ( http://www.newegg.com/Product/Produc...82E16814150229 ) for $149 with a $20 rebate. My question to you, aside from advice on a better video card or a dvd drive at all, is what I should choose (or what I should look for when browsing them as I've never done this before) by way of motherboard, cpu, power source, and whatever else I'm overlooking.
