|You already have a 128MB AGP card (which is rather impressive, considering that the AGP barely worked on many Super 7 boards). If you have an extra memory slot, you could add a 128MB module to boost memory to 512. Turn off XP's eye candy. If you're using AVG anti-virus, ditch it and use MSE. The AVG update process absolutely kills machines slower than around 1GHz with less than 512MB of RAM.|
That's about it. The K6-2 was a slow, slow CPU--even for 1999. Similarly-clocked Celerons beat the crap out of it! If you need some extra computing power, build a cheap AM3 machine or look around for old P4/Athlon XP machines. Not long ago I found a Dell with a 1.8GHz P4, 512MB of RAM and a Radeon 9250 video card--in perfect condition--in our alleyway. Plugged it in and it fired right up to a clean install of XP Pro!
