I bought a rx 580 recently, but my prebuilt computer is not UEFI compatible. I am looking to replace my motherboard with a newer one compatible with my current hardware. I have a 700w psu, an intel i7 2600. I understand i need an LGA 1155 motherboard. Will I be able to keep my current 4 sticks of 3gb ddr3 ram? Also, i read in some cases i may have to buy a new copy of windows. If so, do I have to prepare my HDD in some way, as it already has a copy?
