Ok Ive decided to go with it.
Asrock 4CoreDual-SATA2 Motheboard = £40 - Ebuyer.com
2gb Crucial Ballistix 6400 = £58 - Crucial.com
Intel Core2Duo E6600 2.40GHz = £50 - a friend .com
also realised my sata2 harddrive is gonna be used to its full potential, as current Asus P4P800SE mobo only reads it as sata1 speed. Twice as fast! thats a bonus.
If all else fails i can simply ditch the mobo and keep the Good CPU & Ram!
Building hopefully during the week, ill let you know how i get on.
