So, last night I picked up a mint 2.3GHz DC PMG5 on Craigslist for $20 (came with a 20" Cinema Display It's my first PowerMac and I'm looking into getting a better GPU. From all the research I've done it seems that there's more than 1 variant of the Quadro FX 4500 Mac edition, one for the EFI Macs and one for the Openfirmware PPC Macs. There's no shortage of the EFI variant on eBay but the PPC versions seem to be few and far between and rather expensive.
The 256MB variant of the 7800 GTX for PC's are readily available for a song but I can't find any info about flashing it, all I've seen is people flashing the 512mb version. So, does anyone know if the 256MB PC Geforce 7800 GTX can be flashed for a PMG5? I read somewhere that the 7800 GTX openfirmware BIOS is a modded version of the official PPC Quadro FX 4500 bios. Is the reason the 512MB 7800 GTX works with the FX 4500 rom partially because they both use 512MB of ram?
I also saw a post about the flashed 512mb 7800 GTX (on the TenFourFox blog maybe?) having some artifacting when playing older games. Has anyone else experienced this?
Any advice/experience/info would be greatly appreciated
