If running the operating system that came with your computer or upgraded from it, you better include the price of a new operating system if you upgrade the motherboard. that will add another 100 bucks or so. IMO, stick with what you have until you get a new computer.
Ok so my mb is a Asus p7p55d but I need an upgrade since its getting a little old and doesn't support ddr4, what mb would you recommend I get that isn't too expensive and that lets me fit 16gb ddr4 and 2 gpu's. On thinking in the 100$-150$ range.
