Abit should have put the XP2800 on thier site as fully compatible. It is. Also the Abit NF7-S is fully compatible. I have set up 2 AN7's, and 5 NF7_S in the shop. I had time to play with one of each. The AN7 has everything you can think of in the bios, actually more than anyone would ever need. Dare I say too much? Yes, I think so. Also the Guru feature is a nice idea but is not fully polished yet (may never be). Overclocking ont he fly in the windows environment is a nice idea but several things can happen. For starters, it lends itself to (noobs) using it often without fully understanding overclocking principals more fully (read voltages) - so locks, reboots, and shutdowns are inevitable. The thing about overclocking that any tru pro will tell you is that you want absolute hard bios control over voltages and clock speeds. Also you don't want stock values to be "reset" upon reboot right after you dial in the perfect overclock. You want it to stay as is. So for that very reason the Abit NF7_S remains the nforce2 king. It is still the most stable and fastest/best overclocker aside from the DFI Infinity (which unless you are prepared for a possible headache with beta bioses to get it stable you may have to deal with). Both boards, the Abit NF7-S and AN7 are great. But for ease of overclocking and a straitforward bios. Take the NF7_S. The thing that the AN7 Has is the Guru overclocking feature (that no-one needs), and Gigabit ethernet, and ALC658 instead of ALC650 for the onboard sound DAC. Better get the best nforce2 while they are still being sold. The new breed of nforce2 will have nothing more than Giga ethernet (which the AN7 already has, and onboard onchip firewall (which will be more of a gimmick because most power users that run HS internet use a NAT firewall anyway (if they care about thier privacy). NF7-S remains the K7 king.
