So I just ordered two EVGA Titan X's for SLI.  This replaces my EVGA 980 superclocks.  How much more performance do you think I can expect, also what is the best option to go about selling my 980's to recoup some of that Titan X cost.

That's hard to say given you gave us essentially no information except that you upgraded your GPU's. If you're running them on  a Core 2 Duo...well you won't see much gain. If you're matched with a newer processor running at 4ghz or better, you could see a 15-20% gain in performance at stock GPU clocks. You could check out the EVGA Marketplace for some ideas...http://forums.evga.com/EVGA-Marketplace-f54.aspx
