So I am buying a Crosshair V next week and I want to slowly upgrade a few things. I currently have an Asus 5850. My question is should I get a second 5850 or should I sell it and buy something in the ~$300 range since a second 5850 would cost me about $150. What would I see the best result for buying? Or should I just wait until the 7xxx series is released before upgrading my video card?
