So here i am looking at motherboards and i've found:
http://www.scan.co.uk/Products/Asus-...A-RAID-ATX-VGA
and:
http://uk.asus.com/products.aspx?l1=...21&modelmenu=1
The only differences i can spot are slight layout changes and the ability of the M4 to take DDR2 1200 (which i've never even seen). There is a £30ish difference between the 2. Am i missing something?
