I'm not using my pc for gaming or graphical stuff, so I will go and get an fairly cheap new graphics cart.
I'm just using my pc for playing poker, doing some MS office work and watching video's.
I found this cart on the website of my local computer store for 40€ (55$) -> Asus VGA AMD Radeon PCIE 2.0 HD 5450 512MB.
This will have to do.
Thanks for the answer Wolf
