I was gonna sell my 5850 and someone said that reference are worth more , do you think that someone who buys a $150 used mainstream card is gonna put water block on it?
I threw a waterblock on my 8800GT and overclocked and volt modded the crap out of it. When I moved to an ATI 4870, I kept the water block and swapped cards/cooling and that was it. Moving then to a volt modded 8800GTS 512 I did the same thing, and the same moving to a 9600GT. Moving then to a GTX 285 I had to drain the loop to install a different hold down plate, but I put it back the way it was and that was that.
