I currently have one 580 in my computer, and recently bought a 290. However, I can get another 580 for about 150ish and return the 290 for 500 bucks. Now, would a second 580 be worth it in the long run? Which setup will I get better performance with?
 
+1 to bignastyid's advice, so long as you're ok with some low-level techie stuff and have one of the 290's from a manufacturer who are ok with this mod, ie. they allow the warranty to stay in place (Sapphire is one of these methinks).
