i could be wrong but i thought that Intel was more future proof becuase they are keeping the same socket(LGA 775 for their next CPUs but AMD is going with a new AM3 socket.
ive narrowed it down to 6 motherboards. i know eSATA is the future and my external HDDs have eSATA ports so i would like something with eSATA but i can live without it (and definitely for a couple years). i do know that you can add this with an add on card (but are they PCI? PCI-E? or is it just a cable that plugs into a normal SATA slot?). i need firewire for my camcorder. i really like having lots of USB ports, i believe every computer should have 10

. 4 is fine but i REALLY LIKE that the EVGA has 6

and the lifetime warranty makes me feel a lot more secure buying it so im leaning towards that one. but i dont know about the other companies' warranties.
here are my thoughts on each motherboard:
really cheap and has eSATA, but sound card seems cheap
