Recently I bought Ark 2000PV as it seems to be the fastest DOS card. When I found 1000PV on the net I decided to buy it to compare it with 2000PV.
The conclusion is interesting. It is exacly the same fast as 2000PV (in dos games like Doom - tested on Phil's benchmark set). Do you know what is the difference then between 1000PV and 2000PV if the fps results are the same?

The second card I got today is AdLib clone with Goldstar chip, by date on sticker I think it's from '91-'92. Card is "virgin new" without any scratches on ISA from inserting it to slot.

I just collect the hardware — others make it run.
