Alright, I currently have a 7870 and its performed admirably, but its starting to get a little long in the tooth so I'm thinking about an upgrade. I have around $300 to spend to upgrade and I want to get a card that will last me several years. I only need to reach 60 fps because that's all my monitor can manage and it'll be a few years until I can spend the money on one. What do you guys think? Also, is it worth waiting for the new nvidia cards to come out?
