Got a few choices here.. Asus P5W-DH Asus P5N32-E Plus (with 680, not 650) Asus Commando Asus P5B-Deluxe Abit AW9D-MAX DFI Infinity 975x Price isn't so much an issue. Other hardware going in: E4300 2x1gb Buffalo Firestix PC8000 D9GKX Silverstone ST50EF Element eVGA 7800GT No plans to ever SLI or Crossfire
Commando is pretty over priced, so I wouldn't recommend it. The DFI Infinity is pretty good value, its cheap but still functional. The AW9D-Max, P5N32-E, P5B-Deluxe and P5W-DH are expensive but have good overclocking and features. If you don't need crossfire or SLI then any of them would really do, and since the E4300 has such a high multiplier none of the boards FSB maxes should really limit your overclock. If you want to save a bit of money then DFI Infinity would be the best choice. If you want to get maximum overclocks then P5B-Deluxe or Commando(if you have money to throw away for small feature additions) would be good choices. Really, you can't go wrong with any of those boards, just depends on how much you want to spend.
I'd actually go for an MSI P6N diamond. the on board X-Fi is better than most on-board sound, and the board has an integrated RAID controller thats hardware, not the usual software. the two running modes for the 4 PCIe x16 slots (16-16-8 or 8-8-16-8) also make it a real winner.
I've pretty much narrowed it to those, since they're all available to me in no time flat. The price isn't an issue, they're all within a couple of bucks of each other: P5W: $150 P5N32: $150 Commando: $160 P5B Deluxe: $130 AW9D: $130 DFI 975x: $95
i just send back my DFI p965 board due to noises and usb issues, as well as really finicky bios. (300 and 335 fsb would work, but 333 would not, etc). i wouldn't buy a dfi board edit: i'm now getting a gigabyte p35 board that supports ddr2 and ddr3 - plenty of upgrade paths.
