Turns out i haven't solved the problem. Whenever i try to run a game it gets forced back to 60Hz and ends up looking fugly. I'm currently using my Dad's monitor which uses a normal 4:3 aspect ratio instead of 16:10, and it's absolutely fine.

The only other difference between this monitor and my monitor is that my monitor uses a VGA socket, while this one uses a DVI socket. The only way i could use my monitor with the card was through the use of a an adapter that came in the box, and i think maybe that could be where the issue is coming from, a faulty adapter? Or maybe it just doesn't like widescreen resolutions running at 60Hz?
