hello, I've been waiting to upgrade my music pc for the last few months and have picked out 2 motherboards that I think will serve very efficiently and quickly. http://www.newegg.com/Product/Product.aspx?Item=N82E16813131300 http://www.newegg.com/Product/Product.aspx?Item=N82E16813121338 I've read over basic specs etc for compatibility with the rest of the components I'll be using and they're fine. Is there anything that either of these motherboards can offer over the other in terms of stability and speed. One other thing is SAS drives, will I have to purchase an extra pci card? or will they connect via standard sata? any help would be appreciated.
