Although one cant really say there is a "best" per-se, MSI and DFI make awesome K8 boards, for K7 boards, ASUS and ABit are makes of choiceWhat is the best Brandname for a motherboard.
ASUS hasnt done such a stellar job with their K8s as they have with their P4 and K7 boardsI've been a fan of ASUS and AMD...
They used to... think they got out of it nowAMD makes motherboards?
Gotta be a bit careful with the broad statements. ASUS (and similarly ABit), make awesome Pentium and K7 boards. But they certainly dont live up to their older reputations with their K8 boardsASUS make stunning board which handle great under gaming, DFI is also awesome.
Last time I checked, ABit wasnt a budget oriented companyIf your really on a budget but still want gaming then i suggest Abit, not the greatest ever but it does the job with no frills attatched.
