Damn dude, i'd consider that as well. Even though strobelight is a good enough reason for me to stick with team green.
It just so worked out that it was the only full size standard width card that I could get a clean CSQ nickel/acetal block and backplate for. 780's are cheap enough right now but i've had four already, 970 blocks don't exist yet, 980's are double the price. I am worried about the heat because my cooling solution is going to be extremely restricted but i've seen it done in the past and it works for the 295x2 so i'll give it a go and hopefully it turns out quieter and cooler than stock.
