I have a Gateway DX-4870-UB20P which has a bad motherboard. I've found an Intel board which appears to match the key requirements (DDR3 RAM, LGA 1155, Micro-ATX form factor, USB 2.0 and 3.0) but I'm concerned about whether my Windows load will function. I've read that if you have an OEM install, booting to anything other than an OEM motherboard will invalidate the license key. Is that true? The board I'm considering also has the H67 chipset instead of the B75 chipset of the original. Will that matter?
