I agree with rob423. I'm running the a7v8x right now & it's a fine board. I think everyone is hung on the little performance gain the a7n8x has over the a7v8x. Look at the posts on this forum & the benches here. The a7n8x is a little finicky & the drivers aren't quite up to snuff yet. The a7v8x installs right out of the box with the latest BIOS (doesn't need flashing yet). Load the OS, VIA drivers & rock!!! I believe that a7n8x will mature, but it will be awhile. BTW I'm not anti a7n8x because I'm putting one together for a client, but the a7v8x is easier to set up.
The other thing is, I'd at least go with the AXP 2400 to get the latest Palomino core. I feel that's the lowest I want to go right now in a CPU. The 2700s & 2800s have the 333 FSB, but are to pricey right now in my book. Get the 2400 & after hammer comes out get the 2800 with the 333 FSB cheap. The board already supports 333 & 400 FSB. You got all the speed you need right there & an upgrade path for the future. My $.02.
Signature, I'm still learning & having fun doing it!!!!!!
