spec me a gpu

[Faceman]

Hi all, thinking of building a new cheap system, and have no idea what gpu to use.
I'm thinking of getting a 24" monitor, and maybe adding another in time.
i don't tend to play many games but i do still play wow, got no plans for anything else in the near future. But if i did get the 2nd 24" i guess i would need it to run smooth windowed
Looking for the cheapest option possible, but got no set budget at the moment

Cheers
Steve

Thats great, alittle more than i had in my head, but knowing it will run great makes it worth it
