Using the test results guide here on MacRumors a flashed FireGL X3-256 seems to be a good mix of performance and cost. Looking on ebay there are 2 sellers (old-macs & italod) who regularly advertise flashed FireGL X3-256 video cards. Beyond price $89.00 vs $79.98 (69.99 + 9.99 s&h) I'm trying to understand any difference between these 2 vendors offers. Do all cards use the same ROM? Anyone have experience with either if these vendors?
