My friend had an extra Intel Processor that he said that he would be willing to sell. The only problem is, I'm not sure if my ASUS M5A78L-M/USB3 Motherboard is compatible, or if I need to buy a new motherboard. However, if I were to get a new motherboard, I would need it to be affordable (around 50 US Dollars) and compatible with DDR3. Any Ideas?
