I feel like a made a big mistake getting this PC as it seems to already be obsolete after 2 years and almost impossible to upgrade due to its weird motherboard that cannot be purchased like a normal one. The only upgrades I can use for is the i7 6700k which by itself is over $300 and everything else is just 6th gen stuff that is already dated. It also uses no name brand RAM so i have no idea if it will go with any new motherboard i will purchase. So what is my best and cheapest option for the performance?
