The SYSmark 2000 isn't that important for graphics card reviews. However, I prefer to include the results to show that the performance does not differ even when the range of clock speeds is this large.
The benchmarks show that the latest Golden Sample fails in its mission to reach GeForce2 GTS performance in resolutions higher than 800x600. Still, GTS boards have two disadvantages to speak of: they are much more expensive than MX cards, and they cannot support two monitors. The GeForce2 MX 400 Twin VIVO might not live up to our expectation that it would be the non plus ultra among graphics cards, but it is still the fastest MX card that we have ever tested. Of course, you also get the added bonus of the TwinView feature, plus TV input and output for composite and S-Video. The main attraction is the option of running the chip and memory safely at 250 and 260 MHz respectively. Other graphics cards can be overclocked as well, but only a few companies offer a setting that lets you run the card with stability at the fastest speed possible.
