7870 or 7950?

I've seen some tom hardware comparisons of the two but didn't justify buying either. http://www.anandtech.com/bench/Product/548?vs=550 The anandtech results really surprised me they are both very close but the 7950 gets slightly higher fps in many of the games listed there that I also play. Bottom line I just want to know if the 7950 is worth the extra money.
