you're welcome maynard. the main thing is to find out if the card has voltage control. the cooling can be dealt with later. change the tim, add fans, or water. i am not sure if that card will fit any waterblock or if you are planning on water. still, the main thing is if the card is unlocked.
now, if you are seeking a card for benching, then i will recommend what most others willl - a reference card and water cool it. for gaming, an unlocked ordinary 7970 is best.
btw, that card will take up to 3 slots, i believe.
