ah i see, i though the vapor-x was the same card with a different cooler. that sucks then, getting a card with a better cooler but that you can't overclock?
im not sure how my card will overclcok now, just got done replacing the heatsink with an aftermarket, basically it blew. re-installed the old one but realized i'd broken some of the thermal pads :S
just ran a stress test and crashed the system. hope i havn't broken my card
