@DosFox@tech.lgbt They used MXM? The G4 just had a riser card, I think for AGP. You probably want to mind which models of card were the ones that **all** failed, like I think some late four-digit nvidias and early HD Radeons did. Don't want to get a reballed card bc the actual chips are bad. I think there are other cards that flooded the market because they were fine but some other part of the imacs all failed the same way
@DosFox@tech.lgbt Ah... I should have expected prices to rise. They were all shovelware a few years ago. I think the 9600 and 4670 were good, and the 8800 and 6750 died a lot, but my memory isn't too good on that because I didn't work on iMacs much myself. The GT 120 would be from a 2009 so if you used Leopard 10.5.8 it might work without boot screens.
@DosFox@tech.lgbt Oh, also, keep in mind you're never going to get boot screens on something that didn't come right out of another G5 XServe, because no other Apple product had MXM cards until EFI64 Macs
