	I have experienced exactly the same thing. It is particular bad when
you need to repaint a DOS-apps window. A Windows window is slow but perhaps
just useable. A DOS-apps window can take 30secs to repaint !!!
	I also called ATI and they also said that it was what it was, and
there was nothing to do about it. They recommended using 800x600 mode.
	800x600 IS a slot faster and quite useable. That is the way I use
the ATI card now.

	I have, on another machine, a Video 7 VRAM card. That card is FAST.
Works great with Windows 386, EXCEPT that the drivers have a bug such that
when using the VRAM with DOS 4.01, a DOS-apps always defaults to the A: drive.
This drives (:-)) me crazy. Video 7 claims this bug will be fixed in a new
release SOON.
	Does your VGA 1024i board have this problem ?

	Agreed. The greatest thing about the ATI board is the built in
mouse port which save a board or COM port. Unfortunately Gateway's ATI
board doesn't include the mouse port. This is the biggest beef I have with
Gateway. Otherwise, I'm a happy Gateway customer five times over. BTW, I
hope you got the NEC 3D monitor from Gateway (an extra $100, but worth it.)
	It sounds like you should send the ATI board back to Gateway, get
the $200 credit and get the VGA 1024i (or the ATI with the mouse and live
with 800x600 resolution.)
