Which model is your card? you forgot the most important bit
erm not sure... doesn't have anything listed on the board. both just say asus and has a heatsink. looks like they may be older models of video cards. they don't even have fans
Download and install GPU-Z. It will tell you everything you want to know about any GPUs in your machine, and then some... You don't need to install it, you can tell it to 'just run, don't install", if you'd prefer not to.
Edit: the cards not having fans makes me wonder if they will be new enough to be able to run OpenCL and are capable of mining though
