I can tell you from experience with several video cards that the most important thing you can do to get the most out of it is to rig up an 80 or 92mm fan to blow across the bottom of the card (coat hanger wire is perfect for this). In my opinion, the main advantage to using RAM sinks is that all the chips stay at a more equal temp, which can be important to all the chips staying in perfect phase when being pushed to their limit. I made tall, individual sinks for each chip on my old GF 256 DDR, carefully glued them on with Arctic Silver epoxy, and it didn't help at all. I also glued an Intel retail cpu cooler (came with retail boxed PIII 550 fcpga) to the gpu on that card, and that did help core speed quite a bit. It also blocked access to the top two PCI slots. I would recommend that you get a breeze blowing on it, set it at 200/450, and enjoy it.
