I'd like to be able to raid 10 or 25 on medium/high settings on WoW, along with a number of addons, without getting low fps. I'd also like to be able to run Diablo 3 at decent settings.

I just copied most of the 570 budget computer from Marest's thread (although I couldn't find the case on this site so I wasn't sure what case to use) and was wondering if this would be enough to do that with WoW. I'm also not sure what to do for a monitor. Just something cheap that will display everything fine and not take up too much space. My laptop has 1366x768 (or something like that) resolution, so something that's not too big of a jump would be ideal.
Also, if I already have a windows 7 disc with a key, but the key has been used on another computer, will I need to get a new OS?
I'm also looking for a cheap gaming mouse that has good number of thumb buttons (4+).
This is my first time looking into building all this stuff myself, so any help would be greatly appreciated.
