go for it
I have the P5N32-E SLI and I LOVE it.
I do have a 24" mind you, but with 1 8800gtx xxx at the moment. Once you try a 24" monitor, you'll never wanna go back. I feel like I was half blind before. 24" is where I'm going to stay at... so eventually, I will end up with SLI.
But even without SLI, I still like the dual lan and despite what some people say, stability. I've only had problems once when Vista RC1 came out, but after that... Windows XP Pro/Home/Vista x86/64, I have not had a problem with this board. Right now I'm running 3.5GHZ E6700 on Air (Thermaltake 9700), 45C. I'm comfortable with that. I could clock higher, but I think my RAM is holding me back ATM... 3.5GHZ , is a good spot for me.
If you go Water/Phase and have better RAM than I, I'm sure you'll have no probs OC'ing more.
