I am selling my Ps4 to buy a new graphics card and a power supply for my dell ups 8300. Could you tell me which graphics cards are confirmed working for the xps 8300 ? I mostly want the Gtx 970 but I heard that the mobo has locked Bios. Some people say that the Evga version of the 970 is compatible with Dell XPS 8300. Has anyone successfully installed a 970 on a XPS 8300 with an 0Y2MRG motherboard?
