I looked at the article last night [Shucks, it was on my desk all this
time.] The article is in the July '89 issue of PC Magazine. The performance
benchmarks was based upon both bios and register level performance. 
The Tseng Board and the ATI VGA Wonder performed comparatively about the
same. The ATI VGA Wonder got editors choice because it was also Auto-sensing
multi-switching, which allows it to work with any IBM monitor and because it
has an on board mouse port.

I'm looking forward to the posting of the benchmark you  used.

Thanks.
