Gigabyte Radeon R7 360 or EVGA Gtx 750 ti sc?

GTX 750ti is better card but it requires an UEFI bios(and that could be the problem cuz' cards that require UEFI do not work on legacy bios).
To be sure ,i would go with R7 360 from sapphire because it has dual bios support(it supports legacy and UEFI so it will work on your MOBO)
And what motherboard do u have ,because it may have UEFI and then you could buy GTX 750 ti and roll 😀.
 

Will the xfx r7 370 work as well?
