Personally, I llike (really like) Abit Boards. I had an IP-95 that I adored up until about 7 months ago (outdated, yes, but it suited my needs). It was replaced with an IL9 Pro. Granted, we got off to a rocky start, but I've come to love it, as well. Simply put, Abit = results expected from a well-known, Brand-name company.
However, many people have had problems with their IP35 Board since the day it came out. Not certain if it holds true still, but a few months back, if you went on the Abit Forums and looked in their 'Troubleshooting' Folder, the first three pages were Ip35-related issues. People bought the Boards by the droves, but had a lot of issues with them. They *might* have fixed many of them via BIOS updates, but know you might be in for some fun if you purchase one...
