A couple of weeks ago I asked about what video card might be best for my oldish system, which has an ASUS P5A-B (Super 7, AGP) mainboard with an AMD K6-2 500MHz CPU. After taking the responses posted here, and suggestions of sales reps into account, I decided to get a video card based on the Geforce2 MX chipset. The sales rep at the store I bought my card from suggested a Geforce2 MX 200 card. I figured it would be plenty powerful, being a Geforce2-series card. 2-D performance seems to be equal to what I was getting from my Matrox Millenium card. 3-D performance is better than what I was getting from my Canopus Pure 3-D Voodoo 1 card. (I get faster frame rates from the MX 200 at 32-bit and 800x600 than from the Voodoo 1 at 16-bit and 640x480.) I'm wondering, however, if I'm doing myself a disservice by getting this card rather than an "old" MX, or an MX 400. Tests show that these two can provide noticeably-better performance on a 1 GHz CPU than an MX 200. But I know that my system quickly creates bottlenecks, so there might be little or no performance difference when going from one card to another. Should I return the MX 200 card and get an MX or MX 400?
