I upgraded my comp from a P2 350, 128 mbram, i740 vidcard to an AMD Athlon XP 1800+(notice the hugeness of the upgrade, from wintel to winamd =P!) 256mbram with a NVidia GeForce 2 MX 400, and windows 98 is running slower than ever!
And yes, I am using Linux.
But how fucked up is that, you upgrade your comp and win98 is slower than before you upgraded.
