Such memories! I use to get my dad's old computer hand me downs, first a 486 that I used to play street rod on, then some celeron that I put a 32mb TNT graphics card in somebody gave me for free.
When I was in my final year of high school I used my savings to build myself an AMD Athlon 2500 or something like that with a 128mb graphics card from Nvidia, but not sure witch one, I know it was mid range, I use to play a lot of Unreal Tournament and Wolfenstein Enemy Territory was the first game I played online, thanks for the memories man!
