So my girlfriend gave me a motherboard of hers, a Sabertooth X58, since we both like to build computers. So, now, my problem is finding an i7 for this board so I can actually put it to good use. My question being; Where can I get an i7 in this socket type without having to spend 600 dollars? My CPU currently is an Intel Q9450S running at 3.0GHz, and I'd rather not spend 300+ just to get the same thing, but in a different socket type.
Also, would I be alright if I bought one of the Xeon processors? What's the difference between a server processor and a regular processor; and would a server one be good for gaming?
