But he could upgrade his existing rig to a quad-core with SSD, for some $100 or so bucks. Sure, he won't have the single-threaded IPC of a Skylake Pentium, but overall computing power should be greatly increased with a C2Q. Btw, given the price premium for the Q9650, I don't really recommend it. A Q8400 is 2.66, instead of 3.00Ghz, but it's only $15-20, instead of $50.
And Sheep, you forgot the OS. Unless OP is using a retail license, he won't be able to transfer his copy of Windows to a new mobo, so add $100 onto the cost of your solution, making it $310. $310 versus $100, and keeping the OS install and mobo he has now. Seems like a no-brainer to me. Power-consumption issues with Core2Quad are overblown. It higher idle power than newer chipset, because it lacks power-gating, but power usage under load isn't horrible, when compared with newer chips, also at load.
