Which is better?
 

Got a chance to get either a GTX465 or a GTX560. It's primary purpose/use will be folding as it'll be in a dedicated crunching/folding system I'm building. Which one will yield the best results?

I'd say a GTX560, but in all honesty I don't fold so you'll be best waiting for a fellow folder to answer your question, possibly one who has both of the cards or at least have had. :)

If the GTX465 has a black PCB, it might bios unlock to a GTX470. It will run hot as it is GF100, but will produce more PPD(as much as 17-18K PPD). The GTX560 might be better choice, as long as it is not a cut-down SE model. The 560 is GF114 and will run cooler and be more energy efficient. The O/C'd GTX560 should net 11-15K PPD depending on the work unit.

It's not a unlockable GTX465(it has a blue PCB)

I would get the 560 but only if its a Ti,otherwise 465

i would go with the 5 series just because the power is a killer...

I would also say the 560 only if 560ti, much less power consumption and heat. I dont know about folding but overclocked a 560ti beats out a stock gtx570 in performance.
