gpu n cooler will yield more if sold separately.

7-7.5k shall be cost of HD4850 new one in few days due to HD4770 introduction n GTS250 price drop.

so sell it quick at 6-6.3k wid stock cooler if u have now... or wait for people to wait n buy at that cost later...
8k seems gr8 price wid accelero if it includes turbo module...
