Re: 6800GT stuttering
If it stutters on the new Mobo, while it didnt on the old, it sounds alot like it would be down to the difference in AGP implementation between either the chipsets or the mobos themselves..
Did your old chipset use all the features the new one does?
SBA, FW and such?
you got the propper chipset drivers installed?
might be a idea to look around nforcershq.com forums on the issue aswell.
Does 3dMark05 take CPU into noticable concideration?
seing how 3dmark03 was hardly affected by CPU at all..
