Possibly upgrading graphics card

[Pyro1990]

This is my current build:

and I was thinking about asking for a new graphics card for Christmas but was wondering if it would be better to get a newer video card or just SLI another 660. I can get another 660 for ~200$ on newegg so the alternative would have to be no more than 300-ish to justify the cost for me.

thanks for any help

What games do you play? If it's just for WoW, I wouldn't bother.

I know nothing I currently play would really benefit from it, all the games I have now play at high or better, but was just considering it as it might boost my ability to play something like BF4 or AC4.
