I'd prefer it, except that I don't think I can fix this problem without replacing the motherboard, and at that point I have to replace so many parts that at *most* it might be worth keeping the hard drives and the case. > and a couple of not very easy and not guaranteed to work: > > -try booting with your 5700 in a secondary PCI-E slot and your old > GPU in the main slot, check if Debian detects both video cards, force > certain applications to use new video card and use it like this if > it works.

Thanks for suggesting it, though. > -check if there is a different BIOS available for your new GPU which > enables legacy support. That's a decent suggestion!
