Hi, I'm kind of in the same situation as you. I held myself back when 7600gt was introduced a year ago. 2x 6600gt < 1x 7600gt, now we don't have to hold back any more. 8600gts is coming out around April 17, let's get that one for $200 and move on with our life. Give the 6600gt to an old system, or to a friend, or sell it on ebay. Long live 8600gts.
