My 22" has seemed a little small to me of late so I want to make the move to 24". I now have a single GTX 260 and was wondering if I need another one or swap it with a 4890. I mostly play WoW, but there are some other games I play here and there and there are some games coming up that I want to check out. I like eye candy but with WoW being my main game, I am wondering if it's even worth it to grab another card for 19x12.
