Age old question - GPU upgrade - SLI vs new GPU

[Abstractfear]

Hey guys, sorry to bother everyone with this age old question.

My current build consists of:

i5 3570k OC @ 4.2
Gigabyte GA-Z77X_UD3H Motherboard
XFX 650w PSU - Bronze
EVGA GTX 760 OC
16GB Corsair 1600 CL 9-9-9-24

That should be all listed that matters.

I want a little more GPU power.

I can't decide if I want to SLI my 760 (this would require purchasing a new PSU)
or
If I should shell out for a GTX 970

Opinions?

Also, if I were to go with SLI, what PSU do you recommend?

One powerfull GPU is ALWAYS better than two not so powerfull GPU's. I'd rather sell the 760 and get the 970, its more futureproof and it produces less heat. Also, you need a pretty good PSU to SLI.

"For a system using two GeForce GTX 760 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 700 Watt or greater system power supply"

I would go for 970 o/

That is very true, I didn't think of the option of selling my 760... Thanks!
