I had my 1st PC around 2005, it only had 40 GB of hard drive space that time. I forgot the other specs, but it can play GTA and NFS and other games already, so it wasn't that bad.
My first PC was Pentium 4. And it had some of the good specifications. And it seems like the old computers are not worth it with the specs. I guess on that note I think PC such as old are not worth for gaming.
I had this crappy compaq with 512mb RAM and S0GB storage which ran windows XP. It didn't even have a dvd ROM!
My first pc ran on a floppy disc and the only game that was played was tetris and the pingpong thing. I don't think there was windows way back the early 90s because the screen was even in black and white or green.
My first PC was: AMD Duron 800Mhz 512 MB RAM 64 MB Nvidia Video Card 20 GB HDD 15" Monitor This was back in 2001, the days where I really get hooked into computers and actually missed a semester of school because of it. Good times.
