And I'm terrified I'll mess up. My sister wanted a computer and I said I would build her one for some reason. I don't know, seemed like a good idea at the time. Anyways, she wants a computer for gaming mostly. She's crazy about those Sims for some reason. So I found some computer building sites and it seems pretty easy, so heres what I got so far? eVGA GeForce 6200 Video Card AMD Athlon 64 3000+ ECS KV2 Extreme Via Socket 939 ATX Motherboard Kingston Dual Channel 1024MB PC3200 DDR 400MHz Memory (2 x 512MB) Samsung / 200GB / 7200 / 8MB / ATA-133 / IDE / OEM / Hard Drive Aopen / 52x32x52x CD-RW / 16x DVD-ROM / Internal Beige Combo Drive Diablo / 550-Watt Sabrent 6-Channel 5.1 3D Surround Sound PCI Card Premium 2531 Silver ATX Mid-Tower Case with Clear Side, Front USB and Audio Ports Well, that's about it. Just wondering if it'll be ok to play most games. Just wondering if I got everything for the computer building part and/or every thing is pretty compatiable. Thanks for your help.
