I think you've almost exactly described my Counter-Strike setup 25 years ago.

Friends at LAN parties complained how ugly it was and my rebuttal was usually: "I'm afraid it stays unless you can buy me a better video card." The fact that the CRT slowly drifted to a yellow tinge on everything didn't help the asethetics--especially on de_dust. The GPU at the time might have been a Riva 128 ZX.
