Replacement for Intel Core i5 3570?

Wish to upgrade from this solid little processor. Figured could probably get some bargains as will continue to use my LGA 1155 motherboard. Aiming for used and for under £100, any suggestions?

The best processor for that socket is the i7 3770K, you can probably get it for around the amount you want to spend

Hmmm theres quite a few of those badboys on Ebay and my gosh are they affordable. Outstanding stuff, cheers darth!
