A very solid and cost-efficient card is the Sapphire Radeon Hd 6870, it costs 155 after rebates on newegg and will destroy WoW. Also, I'm not 100% sure I don't play WoW but also doesnt it rely on a good CPU as well? (I'm asking, I do not know)
Also, get a bigger SSD. Put Windows 7 and WoW on that 60gb and it's about full
WoW+Windows 7= 25 Maximum, aka 64 bit Windows 7 Ultimate, fully patched WoW (22 gb's) That's roughly 1 third of the SSD...(Remember, windows 7 recommends 16 gb or space but in actuality is only about 2.6-3 gb's)
