Hi All,
I'm working on a 486 build at the moment. It will be an AMD 486 DX2/80 that will be used mainly for DOS gaming. Right now, I've got a combination VGA and I/O VLB card based on the Trident 9400CXi chipset. It also has an OAK OTI086 chip on the card as well, which I assume may be for basic VGA purposes. The card seems to work well at 40MHz, even without changing the jumper for higher frequency operation.
This is the card here:

It is much faster than an ISA Mach 32 I've tried in the system, but I don't think it's a great card from a VLB perspective. I am thinking of disabling the VGA portion of the card via jumpers and using it for IDE/IO and then using a separate VLB card for graphics purposes. I'm mainly interested in getting the best possible performance out of low-resolution DOS games (Doom, etc). Windows acceleration is a nice-to-have but not my primary concern. Compatibility with some pickier games like Commander Keen would be good as well, as I've had some issues with ATI cards and that title. A decent DAC for image quality would also be a plus. Any recommendations?
Many of the popular ones, including Tseng ET4000 cards are really hard to find here in Canada. I've seen a lot of CL GD5428/5429 cards around that seem to be good performers, as well as some S3 805 based cards.
Thanks!
