Gtx 460 good for folding?

I am currently using an Asus P8Z68 Deluxe Gen 3 paired with my i5 2500k in my current computer.  Soon I will swap it for an Asus P8Z77 V Pro and an i7 3770k.  I plan on putting the Z68 and i5 2500k in my spare phantom case and throwing in an old gtx 460 until I get something better.  

 

Question is, will this be even worth my time?  I know the cpu and board are fine, but I am not too sure about the 460.  Eventually I might buy another 680 to dedicate to the folding rig..  Just not convinced a 460 is even worth my time and energy for folding anything.  I really don't think it will be any good on its own.
