hi mate,
this sunday is swap meet at melbourne showgrounds(hoping you from melbourne).
personally think its the best of all of them.
i have built few pc and like going to lan parties think amd and asus motherboard is nice combination.
http://au.asus.com/products/mb/overview_p4.htm
have a quick look.
as playing games generates a loot of heat proper case, proper cpu fan, silver termal paste(tube is 15 dollars on swap markets).
you will notice when you go to specific motherboard in above link you will notice that new feature they have is c.o.p- cpu overhating protection so you cant burn your cpu
thay q-fan tehnology which automaticlly adjust speed of the fans depend of the conditions.
i built my system on a7n8x-x and xp2600 barton which cost 100 dollars for motherbaord and 130 dollars for cpu.
on cpu have vulcano 7+which i found very good.my temerature stays arond 30 and when playing up to 38c.
this motherboard had an award as best motherboard for value in 2003-4 year.
if you go to the asus site you will find heaps of things.
asus motherboard have been mile in front of the other motherboard in the world.
look results on www.tomhardware.com
