GTX 660 Compatibility With ASUS P5GD1

[FONT=Verdana]Hey guys.[/FONT]

[FONT=Verdana]My current motherboard is a[/FONT][FONT=Verdana]ASUS P5GD1 Pro[/FONT][FONT=Verdana]and my current video card, a Radeon HD 4850. As of last month, the latter stopped working.[/FONT]

[FONT=Verdana]I decided to replace it with a GTX 660 (and eventually buy a whole new rig to install it in), but I don’t know if it will be compatible with my motherboard. What do you think?[/FONT]

I believe it will work, If both are PCIe slots..
