depending on your processor speed (which i'll mention later), you could probably get away with a GeForce 2 MX400, or Ti, which wouldn't cost much... although if you could get a GeForce 3 or 4, or even MX, go for it. i've found nvidia cards have high compatibility.
like decription said, you'd probably be best off using the eVoodoo 3dfx wrapper and the Glide64 plugin. although with that integrated intel piece of crap, you'd better have a good processor. i used to use that... in fact i'm going to see exactly how many more FPS i get with the geforce 2 than my onboard intel
and in order for you to get the most out of these forums, you should include your system specs. the only thing you have is your memory, which reads 80.6 gigabytes. memory refers to RAM, not your hard drive.
