I have 2 computers, AMD and P4, both running 512mb mem and an open 8x agp slot. They are almost identical so to speak except for the Processor/MB. My question is, which computer should i put my Radeon 9700 pro. I never had an AMD before and 2400+ is equivalent to 1.67ghz but based on some reviews i've read, it out-performs most P4?
