Hey, I currently have an emchaine t5212 that has the radeon xpress 200. I play WoW, or at least i'd like to play on a setting other than minimum. My computer DOES have a PCI Express slot. So i wanted to get the GeForce 9500 GT DDR2 1GB 2.0. Do i have to install anything since this is 128 bit? Thanks for any help =)
