My MoBo is a: Gigabyte GA-880GA-UD3H
as you can tell from this picture:
the two PCI-e x16 slots are not next to each other, but every decent graphics card nowadays is two slots wide.
So if I bought an Nvidia GTX 550ti or another graphics card that is two slots wide, does it actually have to be connected to two slots?
If it does, can you suggest any powerful graphics card that doesn't take up two slots?
