i am running 98se too, and i had a radeon le got the cracks etc. and it rolled along pretty nicely. however, i play a lot of CS and the the card seems to struggle somewhat with the new higher poly models and smoke, however, it never droped under 20fps in the most crowded situtations i cant vouch for the MX as i have no experience with it, but you can get a LE for so cheap that you just cant lose. newegg.com is doing some huge deal with referbished ones now too.
