Hi,

Wondering if there is any knowledge out there, I have a Reply80 board in my model 80, with the boring Cirrus Logic 5426. Would there be any improvement in dropping in a XGA-2 card in terms of video performance (speed) ? I realize that both are 1mb cards, ( perhaps the 5426 can maybe be increase to 2mb by soldering on sockets/installing chips for higher resolutions, read something about drivers not supporting this though).

Anyways other than filling in the model 80 with an additional card to cover the missing slot cover, drawing a few more watts, and things looking cooler with the side panel off, would the XGA-2 card perform faster at VGA resolution tasks, eg a game, or Win/OS2 gui performance (not that I'd be able to notice any of it) ?

Maybe I should just try the landmark benchmark and see how many CPS each can do?

TIA,
Jonathan

thanks for the input! Will see if I get some time to fiddle with it and maybe do some comparisons...

We can defeat gravity. The problem is the paperwork involved.
