I am looking to update my HP h8-1020. It has a IPIS8-CU (Carmel 2) motherboard. I know the motherboard is a piece of crap, but I do not want to replace it if I dont have to yet. My Bios is a Legacy Bios and I can upgrade to 7.16. From my research it seems people are having some trouble getting cards to run with this MoBo, but I do not know if its because they are buying UEFI cards or a deeper issue. I would like to get a GTX 760 or a R9 270x. I found a Sapphire Radeon that specifically says that it works with both UEFI or a Legacy Bios, and has a switch on it. I have not been able to find much out about the GTXs. Do you think that the R9 270 or GTX 760 will work? I already upgraded the PSU when I bought the PC. Any help would be appreciated.
