I recently bought http://www.bestbuy.ca/en-CA/product/cyberpowerpc-cyberpowerpc-gamer-xtreme-gxi600-pc-intel-core-i5-4670k-1tb-hdd-8gb-ram-windows-8-english-gxi600/10260853.aspx?path=76432259ecfde1f75285de9efea6550een02 for gaming, mostly playing wow. it runs wow on high with minimum problems. The only thing i can see that needs immediately upgrading is my GPU. Any ideas what GPU i should get. If you see any other things that need immediately upgrading plz tell me and tell me what to get to upgrade it.
