GeForce 2 GTS + K7M here and the only problem I have is that 5.xx drivers in NT 4.0 cause
some flicker on screen when moving cursor over web links.
In Win98 this problem does not exist.
Performance was below average in 3D games until I installed Asus miniport for AGP.
D3D FSAA is buggy as hell but that has nothing to do with K7M.
oh yea... one thing... some games won't work with AGP 2x.
