I was thinking of useing a XFX HD577AZNEC Radeon HD 5770 Xtreme Edition Video Card with a Intel DX58SO Socket LGA1366 Motherboard running the Intel Core i7 920 Quad Core CPU. Just wondering, in the $200 range is there a better choice card wise. Also, I was wondering if the MB will support PCI 2.0. Tiger's page doesn't say it will, but with a board in this price range...? Well... one would think so.
