Asus A8N32 SLI deluxe-sux

[cloakfiend]

I got this board and all is fine apart from 3d/open gl/directx stuff i.e. 3ds max and Games run super jerky when they get a bit complex, i have 2GB of twinx corsair xms 2.3.3.6 RAM (1 1GB modules) and seasonic 600W PSU, amd 4400+ x2, sapphire Radeon x1900xt 512MB, winxp pro sp2, and i cant seem to run anything with anti aliasing even at x2! its jerky enough as it is, done all upgrading and drivers and optimisers....etc

do i need to do anything to the bios settings to make 3d apps run properly or should i just burn it and get a better mobo? read lots of negative stuff now, mind you i need one that supports 4 sata 2 drives dual channel ddr400 ram and is rock solid. not fussed about oc'ing.

any help would be much appreciated.
