Do not buy the ati 3450 it's a piece of junk, if you want a graphics card that will max out WoW(which is pretty easy these days), you should consider a graphics card in the $100-150 range to be safe and if you decide you want to play a game other than WoW. I suggest Something such as the ATI 3850, Nvidia 9600 gt, Nvidia 8800gt/9800gt, or if you got around 200 bucks for a video card get the 9800gtx(this is a high end one, will max out games like far cry 2, check it out if you haven't). Make sure you have 2 gigs of 800mhz ram, 2.4ghz dual core cpu, and a 500 watt power supply (possibly 550-600 if you get a 9800gtx), motherboard with a pci express x16/2.0 slot.
