I'm not sure but I think Epox has problem with GF4 too, it's the capasitor that too close or
something like that, and my personal experiance and some from the forum Abit has problem
with Audigy(Creative in general)
SOLTEK SL-75DRV4 $92.00
SHUTTLE AK31A $76.00
Those two is good for under $100 I believe,
If you want to spend little bit more I suggest
IWIL XP-333 I believe it's around $110
it support DDR PC2700 and the best on overclock
it has 1/3, 1/4, 1/5, and 1/6 PCI divider while most
mobo including my KR7A only has 1/3 and 1/4
"...we should never forget about the Iwill XP333-R. The board offers a lot of room for overclocking, and its performance is on par with the KR7-RAID. It does not have the same level of flexibility withe KR7-RAID in terms of memory bandwidth, but it does overclock better and it has very nice integrated audio device. Both boards offer the Highpoint HPT372 RAID controller, which is a plus, but keep in mind that the XP333-R runs at around $40 cheaper than the KR7-RAID." -- anandtech.com
well good luck on mobo hunting
