Okay, I have a pretty old computer. However a lot of my games run well, even with the settings almost maxed out.
The problem's that my games look dull and boring, and some don't even run because of Pixel Shader problems. I was wanting to upgrade to a graphics card with a little better specs, so I can play games such as Portal, EP2, etc.
So what I wanted to know, is that if I get a new graphics card, will it work even though my computer is pretty old?
Some basic spec are 640MB RAM and a Intel Pentium 4 CPU 1.80 GHz processor. And my (terrible) graphics card is an Nvidia GeForce2 Mx400.
