You should get a HD 4870 X2 if you can... but if you're only gonna use it to play WoW it's a huge waste of money. I think you only need a 9600GT or better yet a 8800GT for at least future proof. You whole system is future proof excluding the GPU. I can let you download some of my games (I'll upload them) like GTA IV, GTA VC. GTA SA, Crysis Warhead, Crysis, Far Cry 2, Far Cry, Hitman Blood Money, Oblivion, splinter Cell Chaos Theory, Call of Duty 4, Call of Duty WaW, Call of Duty 2, Call of Duty, Mass Effect, and other more.... there big files though and there really GPU intensive so you can have a bit more fun and happy with your purchase on a HD 4870 X2. I mean you have a gaming PC that's meant for these games not WoW if your gonna just play WoW get a PC with a 2.6GHz dual core processor, 2GB or 3GB of RAM, and a 8800GT plus 600W PSU and you don't need Blu-Ray drive it's a waste of money you should get a Blu-Ray player not a Blu-Ray drive there roughly the same price while blu-ray players ouput better images sometimes since I notice blur when connecting my PC to my 50-inch, 42-inch, and 47-inch HDTVs (all 1080p) especially at 1080p resolution and they always recommend that you output resolution at 1280x1024 when outputting using a PC while Blu-Ray players can ouput clear 1080p image on an HDTV since its meant for it but I might be wrong with all that that's just my experience on using an HDTV as a monitor on a PC and viewing Blu-Ray on it vs. using a stand-alone blu-ray player
