my (well, really "our") first card was an Nvidia TNT2 Riva 32MB in a Gateway system with:
Pentium 3 500MHZ
12.7GB hard drive (which died and was replaced with a 40GB Seagate)
4x4x24 CDR/RW (which died and was replaced with a sony 52x24x52 drive)
8x DVDROM (which died and was replaced with an LG 16x dual layer DVD burner)
Windows 98 SE (now XP Home)
it is still the family's main PC
then I got my own computer, which is:
Nvidia TNT2 Pro 32MB (as opposed to the RIVA, what a huge upgrade!) which I overclocked to 180MHZ/200MHZ from 142/150 (core/mem)
and 700MHZ Pentium 3 (now 933MHZ, overclocked to 1050MHZ)
160GB Seagate hard drive
