There are a lot of good boards out there.Go to say Tom's Hardware or Overclockers,Extreme Tech or another recomended site where they test the latest mobos.Usually there will be 4 or 5 top rated with the latest updates.Personally I like Abit,but I have built Epox,FIC,ECS,and some not so reliable brands.Chip speed is a factor but look for features such as serial ATA,USB 2.0,fastest FSB,RAID,8x AGP,1394a firewire.New out are the Nforce2 Nvidia mobos which have 6 top contenders.Abit NF7-S,Chaintech 7NJS,Asus A7N8X,Epox 8RDA+,Leadtech K7NCR18D pro,and MSI K7N2.Those are AMD based.For Intel There are Intel D850EMV2,Asus P4T533-C,Iwill P4R533-N,DFI NT72 SA,VIA P4PB 400,Shuttle AS45GTR.Those are the best so far,in 3mos. there will be a new batch.
