My first PC ran DOS 3.1 on a 80x88 Tandy 1000. Talk about slow! I rocked a 486 25mhz for a long time when I was a kid, slowly moved up. I think I paid $100 for 4mb (might have been 8) of memory at some point to run the first Need for Speed demo. I remember being reluctant to upgrade to Win95 for the longest time.
Now I am CHEAP when it comes to PCs. My current PC was used, I paid $100, but it's a 1.4GZ, 512MB DDR of ram, 60GB HDD, 128MB ATI video, etc. My last PC was a Duron 1.1GZ, 394MB SDRam, 128MB GeForce, etc. Huge improvement... I just cobble parts together for the best machine I can build out of what I have availiable. I couldn't see my self buying a brand new machine, it will be obsolete as soon as I get it out of the door. Computer parts loose value worse than cars.
