According to game-debate , the gain from an I5-2300 to an I7-2600s would be a measly 20%.  In other words, 1.20x the performance.  Barely noticeable.  Going from quad core to quad core usually doesn't yield a lot of gain.

39% with the non-S version I7-2600.  Not sure why speedstep thinks an S version is the max for your DT.  It's the max for the USFF.

I don't think you can use a 3rd gen cpu, but I could be wrong. Even if it would work, there would be little if any gain. Even going to an i7 second gen wasn't enough to be worth the cost and effort for me.

If you need more performance, the best approach is a newer machine. There are some pretty decent refurbs available these days.
