So my MDD model with a GeForce 4MX came recently, and I'm starting the upgrade process. he graphics card is one area of interest for upgradesthe model could take a GeForce 4 Ti or a 9700 Pro, which are both 128MB cardsbut actually *finding* Mac versions of this cards is proving difficult. Anyone have any tips on vendors or resellers besides hoping they randomly pop up again on eBay? Alternatively, what's the situation with using PC cards (I'm only up-to-date on flashing and such for modern AMD/Nvidia GPUs in Intel Macs.) (Also, am I correct in assuming that there never was a Mac version of the ATI Radeon 9000 Pro that came with 128MB VRAM? MacTracker and EveryMac show that at least the BTO and configured versions only came with a 64MB 9000, but I found one or two eBay sellers who are selling a 128MB Mac variant, theoretically.) Also, is there any potential compatibility issues with the newer GPUs and OS 9? I'm intended on running a full install of OS 9 alongside newer versions of OS X.
