In the last 10years thAT I remember, I went from some 32MB geforce type, to
geforce 2 MMX440 64MB
ATI x1350pro 256MB
5670 1GB
6950 2GB then crossfire
7950 3GB now crossfired
Depending on how they do with 2560x1600, I should keep them until mid 2014, but I like to sell them before they break or loss most of their value
Way before all that it was commordore64, then something in a 486DX2 66MHz, then something in a "pentium" 100MHz
