Pure curiosity, same as Sash. What GPU are you using?
Name/model of the GPU you are using in your main PC. You can also list other GPUs in your other PC(s) too.
How long have you had it for?
How much did it cost you?
Do you overclock it, if yes what speed?
Main reason for buying it at the time (For example: exclusive features, best value, or best performance for what I do, or best in budget, etc etc.)
Are you thinking of upgrading it, if so, what interests you the most out of current GPUs, or future ones?
