If this is your motherboard, the fastest supported CPU is the Intel Core 2 Extreme QX9770.
However these CPUs are over $200 used, which is stupid. https://www.ebay.com/itm/Intel-Core...105540&hash=item5219fdab0b:g:B8QAAOSwFpddEfaw
Look for a CPU like a Q9550 which is not far behind in performance but literally 10 times cheaper.
