It that computer is a piece of crap, what is my 350 Mhz AMD K6-2. Ahh so many memories, trying to force it play games, having to set process priorities for some games to get a decent framerate, then having the game crash and not be able to get back to the desktop thanks to the priority, Blue screens with any MIDI file.
I used that for seven years and only for the last two did I think I needed a new computer (mainly motivated by Visual Studio 2005). So then I got another "piece of junk" a Dell 4400.
This is all relative, I mean I paid almost 100 dollars for what I THOUGHT was at least a 500 mhz P2, but I start it up, and it turns out to be a crappy cyrixM-II. great, just what I need, a processor from a non-existent vendor.
If I had a computer like that, my first upgrade would be memory, and then Video card- all the games I play are much older and run in the high hundred FPS (FitzQuake,Quake 2, Doom legacy,JDoom duke3d....) so a newer Graphics card would only help with some of my newer games.
