You can sell if for whatever you can find someone willing to pay for it. Rough guess, probably no more then $200 or so. I bought a C2D CPU with 2 or 4GBs of ram and a 2600XT probably a year or so ago for $200. That laptop isn't much if any better. $250 is very possible, but you probably won't see anything higher then $300 for it. Of course a sucker is born every minute and local markets can very so anything is possible.
