I've got a 2.66 MP that I bought around August this year prior to knowing about the odds of a product refresh in the coming few months (oops) and now I'm starting to wonder if it's worth trying to sell it before the new model comes out. What do you think? I realize I would take a bit of a loss, but maybe even with the loss it would be worth the upgrade. For example, I've wanted to upgrade to the x1900xt video card (they shipped my MP before I could have them change my order to that card to start with). That upgrade in itself would be costly and wouldn't even make sense anyway at this point because of the aging card. I've also added four gigs of RAM for a total of 5gig so maybe that would help offset costs. Would there even be much of a demand for selling a very lightly used, perfect condition MP that's still covered under the original 1 year of Apple Care?
