Re: Ram choice
I really don't see any reason to watercool memory unless you're going to push really high voltage through it. I've ran Ballistix up to 1100mhz and Dom's a bit higher than that w/ 5-5-5-15 and never needed anything more than active cooling for them.
Theirs no reason to go with 900mhz over 800mhz. That's only 100mhz more and it's not going to net you 1fps more in a game. 800mhz @ 4-4-4-12 1T is going to do you just fine. As we've seen in multiple benchmarks DDR2 800 4-4-4-12 is going to perform just as well as DDR2-1066 5-5-5-15. But if you're going for as much bandwidth as possible, I'd pick up some DDR2-800 4-4-4-12 PI-Blacks and OC the heck out of em. They only take 1.8v-1.9v, so you should be able to get a nice OC out of them. But this is just one mans opinion.
I'm not sure how the current Dominators are, but when I had the 4GB DDR2 1066 5-5-5-15 I was able to run them down to something like 4-3-4-9-ish @ 800 and on the other end of the spectrum somewhere around 1150-1200. I'm sure I posted this somewhere on the board about a year ago. If they're still this good, it may be worth checking out. They are $80 so they're a bit more than other good OC'ing DDR2.
