NVIDIA 800800 GT SUPER 1GB

what error message are you getting?

I FOUND AWAY OF GETTING THE SIMS 3 WORKING. AFTER YOU INSTALL IT YOU HAVE TO GO TO YOUR DESKTOP CLICK THE ICON RIGHT CLICK MOUSE AND SELECT RUN IN 256 MODE OR 640 X. THESE MODES WORK, YOU CANNOT WORK IN IN ANY OTHER GOOD JOB I FOUND THIS WAY. I WISH I HAD KNOWN ABOUT THIS BEFORE I BOUGHT TWO VERSIONS AND LOST A TENNER SELLING IT TO A MATE!

You shouldn't have to run it 640x480 resolution. i run mine at 1280x1024 with no problems. have you installed the latest release of directx for your machine? what OS are you running?
