Hi, i have a cheapo 400W PSU with no PCIE power connectors and i would like to get a GPU that doesnt need any external power connectors. What is the best ATI card that i can get? I only want ATI because i would like to get two of them to run in crossfire. This leads to my next question, would i be able to run two cards in ccrossfire, even though they dont require power connectors? Thanks (only crossfire because my mobo doesnt support SLI)
