I'll follow Dee-ehn's advice and go for the msi or the asus (as 2nd choice).
Whilst were talking amd64 systems, can Dee-ehn (or anyone) tell me if i will actully notice the performance difference when using branded cas2 ram instead of unbranded (probably cas3) ram, bearing in mind I will certainly not overclock the memory (or anything else)? I am willing to risk compatability for price, assuming negligible performance differences. My main uses will be playing ut2003, burning dvds/cds, internet browsing and occasionally using DVDxCopy/CloneDVD.
@jmike314 + diizzy: i can understand that sis chipset may have a decent reputation with the amd64, but i am going to go via because [a] via has never trounled me in the past [b] via boards are more available around me and [c] because more people seem to be going down the via route so if i have trouble it will be easier for me to ask for help.
(BTW if anyone is wondering why i seem to be asking about an amd64/VIA K8T800 chipset system again after a few months, it is because I was ready to buy a system in about March but my funds got taken elsewhere at the time )
