You will want to use fastvid and mtrrlfbe in order to get the most out of your CPU:

Sometime around maxwell nvidia removed a bunch of legacy VESA modes from the firmware. Everything you see on a 1050ti will be scalled in hardware, which probably hurts performance.
Despite what you might expect, the 2d performance on modern graphics cards probably isn't any better than on retro cards - possibly worse. None of those shaders are going to be put to use.
You can still run CPU benchmarks like speedsys if you want, but I believe speedsys will glitch out with really fast CPUs and give you a bogus score.
Getting the fastest DOS computer "just because" is actually harder than it seems. My guess would be an older system with AGP will probably score better in something like 3d bench. Maybe an S3 Savage 3d card or something of that era will be the "fastest" but its hard to say.
