If you can spend the cash. But if you're not really doing anything capable of actually doing stuff with all that power (and cores, of which there are now 6 (12HT) of (8/16 for extreme edition)), then it might be worth waiting for the i5 series on that socket. A good i5 will always outshine a middle class i7 when only gaming is concerned, since almost no game uses multiple cores. Very few actually use more than one, so even a "high model number" i3 is not the worst option.
If you can wait, I'd sit still until i5 is going 2011v3. Also, I'm not sure if you want to upgrade your GPU. A 750Ti isn't really bad, especially not for the games you mentioned. If you don't really feel the need for an upgrade there, maybe holding back there until the next generation of GPUs is out and get a 970 or 980 for a more reasonable price.
I've read about issues with SLI/Xfire when it comes to WoW, so much that some tend to disable it there. I have no first hand experience here though. But I always felt like it's only really a thing for total nerds that want to string together already high end models for super duper uber power. In my mind, for example, a good 980 dominates 2x970. Even if the numbers may tell a different story - I don't have them right now. But the hassle of it and also the demand from the PSU and dependence on a board supporting your specific cards well... meh. I'd rather get one really good one and be done with it. But a 750Ti surely isn't too old at the time. (Especially considering that there is no 8xx series, so it really is just one gen behind.)
