I've picked up an ASrock Extreme6 LGA 1366 thats got an i7-940. Was quite looking forward to doing something with this however was a little underwhelmed. Thats was until I discovered that I can put a Xeon in it to potentially give it a decent boost. Prices for all xeons are less than $50 from Ali Express but just wondering if there are any traps to look out for. My board's CPU support list says X5650, X5670 are supported but do I need to stick with these or is any Xeon in the X56xx range ok? Are any better overclockers than others? Any suggestions?
