I'm using a Toshiba Satellite A215 that was made in 2007
1.7 ghz AMD Turion x2 dual core
4 Gb memory
Radeon x1200 integrated graphics (shares system memory).
In the past I've also used an old Dell Inspion before it fell apart. It was probably made in 2003 or something. It actually ran C2 ok, but I'd run out of vram at times.
1.5 ghz Celron processor. Single core.
1 - 2 Gb of memory. I can't remember which.
Integrated Intel graphics. Shared memory.
