I have the following in systems at home-
Asus A7M266
Gigabyte 7DXR
Epox 8K7A+
Gigabyte 7VTX
All of these boards are very stable, well manufactured, and offer excellent performance. Each board has its advantages along with certain quirks. You cannot go wrong with any of these choices.
Asus A7M266- excellent stability, very good performance, top quality components everywhere, funky layout, does not have multiplier adjustments unless modded.
Expensive. Limited Supplies at times.
Gigabyte 7DXR- excellent stability, top performance, top quality components and layout, on-board raid (promise 20265r), upgraded on-board sound(ct5880), blue, three DDR slots (really need registered memory for all three), requires a combination of jumpers/bios settings for tweaking.
Expensive. Very Limited or Zero Supplies. Did I mention blue?
Epox 8K7A+ - very good stability, very good performance (best board for high FSB ability), quality components and layout, on-board raid (hpt370), requires a combination of jumpers/bios settings for tweaking.
Reasonable cost, excellent cost without raid option. Available.
Gigabyte 7VTX- excellent stability, almost top performance (with same FSB settings, best performance) , top quality components and layout, upgraded on-board sound(ct5880), blue, three DDR slots (do not need registered memory for all three slots), requires a combination of jumpers/bios settings for tweaking, lacks CPU voltage adjustment.
Reasonable cost. Available but limited vendors. Did I mention blue?
My favorite at this time is the 7VTX because I can populate all three memory slots (768mb) which helps since I run W2K. It also offers the best overall system performance in my opinion along with the fact that I can use the on-board audio for about 95% of my needs. I still prefer the add-in cards for audio. I wish it would have had a raid option so I could utilize more IDE devices without adding a card.
If I could only have one board out of the group it would be the Gigabyte 7DXR with registered memory for all three slots.
