Sorry, I should have stated. The CPU is a i5 2500K @ 4Ghz. The power supply is generic Rosewill with something like a 16a/15a split on two 12v rails. And I'm going to be sticking with a 1920x1080 resolution.
Edit: Also, is there a reason the 960 has remained absent from the benchmark compare tool?
All the Fury-this and 980ti-that is just noise to me. This time last year I thought I'd picking up a 960ti on a coming black Friday deal. Here I am a year later feeling like I still have no good options.

A base 960 looks like the best of a bunch of bad ones, is there anything else that's actually worthwhile even on the radar?
Oh wow, I was in almost the exact situation about 2 months ago you are now. I had a 2500K at 4ghz, and a 7850 GPU, gaming at 1080 and was feeling like I needed a little more power. I did have a slightly better PSU though, an EVGA 500W with a single 40A 12V rail.
I was waiting on the 960ti/965 to be released but that turned out to be vaporware. After a lot of thought and debate, I ended up with a 960. It offers about 50-60% more performance over the 7850 at 1080p and is even lighter on the power draw.
Right now, if I had to do it again, It'd be a toss-up between the 960 which can run as low as $180 (crap, sorry the sale on the evga on newegg is over, only the Zotac at $190 right now) or the R9 380 at about $200. The 380 has a bit of an advantage over the 960 in most games, and would probably scale better if you ever decide to go to 1440, but the power draw is considerably more....110W for the 960 (gaming) vs 190W for the R9 380 (gaming)
If you're confident in your PSU, and want the most bang for your dollar, I'd suggest the R9 380, if not, the 960 is not a bad card, I chose it and don't have any regrets.
If you can wait however...there's always more fun stuff down the road
