Well, sure it would be kewl!!! I would love to have that stuff. It doesn't MAKE you kewl though. I am kewl because I have reliably overclocked my current config to stomp comparable setups. I make do with what I have, and what I have is still pretty nice stuff if I do say so myself. And yes, I would brag if I had a PCIX board, but I don't think I would feel superior to anyone else though, that's just not me, I am poor, but I have nice stuff, I save up and I try not to show off, unless there is a thread that lets me show off without coming off a egotistical arse.
Let's just say this, if and when I get a board with PCIX next year, and if it has a 939 chip, I will be very, very proud of my setup, as I am with my current setup.
