I actually have the A7N8x-Deluxe and have for about a year now.. mine's an older rev 1.3 board that does not technically support 400FSB (though it supports DDR400). My friend has an NF7-S and he likes it quite a bit... Both boards are excellent boards, but I think I like the layout of the ASUS better. The one advantage the Abit has is the P4 connector for the power supply, something mine doesn't have. On my board the ATX power connector is near the top right of the board, while on his it's down and to the left from the CPU. The Asus has dual LAN and 4 USB on the backplane + 2 on a header... the Abit has single LAN and 2 USB on the backplane + 4 on headers. Also, on the Asus, the location of the fan headers is different.. CPUFAN is above and to the right of the CPU, PWRFAN + CHAFAN are oriented horizontally right next to each other directly above the AGP slot... on the Abit, CPUFAN is to the left of the CPU (below the power supply), CHAFAN1 is oriented vertically just above the ATX power header (down/left from CPU) and the PWRFAN header is also oriented vertically just below the ATX power header. Also, as previously mentioned the Asus has a passively cooled northbridge with a decent sized heatsink and the Abit has a small fan on top of an almost nonexistent heatsink. Contrary to what was stated above, the Asus can also be flashed from inside windows using Asus's utility called "Asusupdate". I've been doing it ever since I got the board and have had no issues so far. Asus also has a decent enthusiast community that's been producing a few "hacked" BIOS's (the best of which is the Uber series), one of which I am running. Asus includes the 4 mounting holes around the CPU for large cooling solutions and waterblocks... Abit started including them from rev 1.2-on, so you should be ok if you get a 2.0. Needless to say, about the only thing I've found on the Abit that my Asus doesn't have is an optical digital out on the backplane itself instead of requiring a header. Asus also seems to update BIOS's more often, so take it as you wish.
