Ok, my custom built computer is a little dated. In the last two years the only two items that I've upgraded were the motherboard and the RAM (8 gigs of DDR5). I currently use an Intel 1700 I think it was (purchased fairly new three years ago [just before Cata was released]) and an ATI Radion 5700. I mostly play WoW on my computer, though I have started playing a few other non-graphic heavy games (I think my most extreme is Mass Effect 3). Basically I feel like the upgrades in Mists are starting to hit my performance in game and I would like to slowly upgrade my equipment and trying to decide whether to go with the GPU or the CPU.
