Hi all need some advice. First off I have a XFX HD Radeon 5870 1g card in my rig now. I am having small issues with it as alot of people are. Here is my question : I received an email from Newegg and they have a combo deal for 2 PNY GTX 460's for 389.99 after rebate. Would I be better off getting these 2 cards or just spend the same amount for 1 GTX 480?
