Well, the refresh rate in Hz is a very important part of the installation! What I would recomend, is first making sure you are selecting the proper video card (find out the exact chipset and such it is using -- you may need to check out the manual or even open the box up and look at the card itself). As far as the refresh rate -- that is specific to your monitor. You can either just select a generic monitor at like 1024x768 at 60Hz (most cheap monitors will do this) or my reccomendataion would be to look at the model number on the back of the monitor. Then look up your monitor on the internet and get the specs for all the info. With a Voodoo card and even a half-way decent monitor, you should be able to get the resolution up to 1024x768 (at least). This will allow the whole screen to be large enough for your apps. Hope this helps!
