I have a computer about 4 yrs old with a pentium II processor,and have been upgrading a little at a time,more ram and a new video card so far. I want to put a bigger hard drive (Maxtor 30 0r 40 GB) will a 7200 rpm make that much of a difference over a 5400 rpm with the processor speed that I have? Also I"m running Windows 98 I read some where that that will only handle a hard drive that is so big.I plan on making the new drive the slave as I can not locate my windows 98 disc that come with the comp.With it in the slave position does it need an operating system installed on it,with out the operating system on it can I run programs like microsoft money and microsoft works on it? Or will it just be for new programs and games that I install on it.I currently only have a 6 GB hard drive (not sure what brand)will there be any conflicts if they are not the same brand hard drive.Any help will be greatly appreceated.Thanks
