I've heard some of the more recent Celerons aren't terrible, but they've got such a horrid history for performance that I wouldn't chance it.
Honestly, for a client like WoW where most of the actual data processing is done server-side, the processor isn't as important as the graphics card. Pretty much any modern processor that has two+ cores and supports DDR3 should do fine. I wouldn't look at any processor that's much over $100. Hell you can get a Bulldozer for ~$100 and that's quad core, 3+ghz, more than enough for WoW. The i3 you linked would be good too. If WoW is your only consideration I'd go moderate with the processor and spend as much as your budget allows on the graphics/memory. Of course that's easier said than done with pre-built systems as the hardware tends to have an overall performance value in each machine (I.E. you're probably not gonna find a machine with a crap processor and 8 gigs of ram and two graphics cards).
