My pick would be the Abit IC7. I love my Abit IS7. The layout is near-perfect from my stand point. My only beef is that the AGP is close the the DIMM slots, which makes adding or removing memory take one extra step becuase I have to remove my video card (GF4 Ti4600). Other than that the mobo is perfect. I love Abit's BIOS and their tech support/RMA is great.
My Abit IS7 had a problem where BIOS would repeatly give me BIOS Error, Checksum error. After talking with tech support, I remove the mobo from the case to see if I was shorting on the case. I RMA the mobo there affter. The replacement mobo functions without an problems. 100% stable with GAT=Turbo with relaxed memory settings. Get the Abit, u won't be sorry.
