if it's legit, $50 is one hell of a deal. but people on craigslist are shady as hell. one time i sold tickets, and got fake $100 bills, and didn't realize it until i deposit it at the bank
. then a few weeks ago, i tried to buy a 5870, and the bitch tried to hustle me and brought out a 5770 instead. he pealed the sticker that marked which kind of card it was, and i told him why he peeled it off. he told me it was starting to rip, so he just peeled the whole thing off. i told him it was also too short to be a 5870, and only had 1 power connector, all 5870s have 2 6-pin power connectors. i obviously didn't buy it.
it's a good deal, but just be wary of the legitimacy of people meeting in local places like this. i'm not sure how u can just bum electricity off mcdonalds though.
