Don't know where exactly I should be posting this, so I'm putting it here since I'm mostly looking at/for graphics cards. Bought a pre-built PC a while ago, (I KNOW, I'M SORRY) linked here. Apparently it runs a gigabyte ga-78lmt-usb3 r2 motherboard, an AMD FX-6300, and an AMD Radeon RX 560-B as best I can tell. I have a few questions so I'll just list em below. When I upgrade this trash can, do I need to update my BIOS? If so, how, because google has been useless. What should I upgrade to to improve gaming & streaming? Got about $750 to play with, was looking at a GTX 1070 but I'm pretty lost.Is GPU or CPU upgrade the way to go? Would most AMD compatible graphics card work with this? Because I see that UserBenchmark says that they all are, but from best I can tell the RX 560-B is a cut-down version of the normal RX-560. Would there be a spacing issue even if I still have room in the case to mess with? Anything else you guys can tell me about general advice or what I should be looking for would be really appreciated! Thanks and be gentle about the pre-built thing, I was broke and stupid.
