Currently I have a Gigabyte Ga-7n400 pro2, and I've been wanting to upgrade it, so I can oc my processor. So I was wondering what the best mobo is for oc'ing on a socket a.
I'm in the same situation as you. I've been looking at old posts in the forums and have found a lot of recommendations for the Abit nf7-s rev. 2. I've found them at newegg for around $85 or on ebay for $65. I'll probably get one off ebay this week.
I've been able to oc on my 7n400 pro but the board's been somewhat of a disappointment. Things are running fine now but I've had some issues with it. I'd like to see how high my 2400xp-m goes on a more stable board.
The main problem that I know of with the nf7-s is that the active cooling on the Northbridge uses a sleeve bearing fan that almost always dies within a few months of purchasing the board. If you do choose to go with this board I would buy a passive nb cooler right away and replace it before using the board (otherwise you should at least keep a close eye on the Northbridge fan and wait for it to break down).
My experience with the A7N8X-E deluxe has been very good. I have had no difficulties with the board whatsoever and would recomend it to anyone.
I purchsed the DFI nf2 Ultra-B board with a XP3200, and had nothing but trouble with it. After that I swore never to purchase DFI again. And since then ive owned the asus one mention aboved and the Gigabye pro400, both have worked really well.
