ok lets say you get a x800xt, it really doesnt matter what make or brand right now since they all use the same reference cooler from ati. Ive noticed on the back of the card (other side than the reference cooler) you can see 4 of the memory chips. Would there be any point to puting ram sinks on these 4 chips to help heat disapation and would it lead to a higher/better overclock? i hope this isnt a dumb question but i hope i get a good answer.
