I've thought about it for awhile now, and each time I go back to the OC reviews.
What are my upgrade choices coming off 7950s? R290 is a downgrade, R290X on reference even with an OC is too.
The only single card option that even can be considered a side grade to 7950 CF is the 780 Ti OC.
Personally I didn't enjoy 7950 OC CF that much, it's a lot of heat, more noise, some bugs, and lot of quarks I didn't care for like having to disable ULPS, not having UEFI voltage control..
Is 7950 CF to 780 Ti OC a side grade? I think it is, maybe a minor upgrade at the end of the day but certainly nothing to write home about.
So why pay $700+ for the Ti over the R290? Cooler choice is the first and most obvious. Then there is the fact that the 290/x is a downgrade in almost every way to 7950 CF, even in mining a decent 7950 can sustain 700 kh/s, most R290/x are only hitting low 800s. No non reference options except expensive third party coolers or water, even with looking at the all OC results across the web the 780 Ti REFERENCE OC is better than R290X OC on water...
So basically the logic is simple and two fold, to get any kind of performance increase out of a single card you need to go 780 Ti, to get close from AMD you need a R290/x with water. When it's all said and done why not? You made bank on your 7950s which were worth about $160 two weeks ago, enjoy what you got... Treat yourself.
Personally I sold mine for almost what I paid for them, I could have gotten more but felt bad for various reasons.
You might have noticed I completely ignored the $500~ 780's... The reason for that is because it's in the same boat as the R290/x, it's slightly faster reference vs reference /w OC and similar on water comparatively. Water isn't an option for me personally, so that rules out basically all but one.
GTX 780 Ti basically costs me nothing, because of what I got for my old 7950s due to miner demand, and from what I stockpiled in LTC when nobody wanted anything to do with it. Heck I came out way ahead on the whole deal... So why not enjoy the best that 28nm has to offer, and enjoy your little monetary victory?
I would never reach into my pocket and pull out $700+ for a video card, no matter how fast it was. However the way I obtained the money it almost feels like I'm paying with monopoly money.
You only live once, if you aren't living hand to mouth why not?
