Monitor is to small imo, if your running single screen it will be slightly crampped and you will have to use maximizer or windowsnapper and the first is pretty slow.

I would also recommend a Solid state disk for wow to run on. I have that processor and with everything going im about 50-60 avg on core usage and about 70% on ram with 5 going + fraps.

Can play it fine, but if I were to change one thing I would have gotten x2 24" monitors.
