Is there any disadvantages of mounting gpu vertically?

If you like being a trend follower then no.

Nope. My core p5 had a bracket specifically for it. If anything it would take some strain of your pci-e.

 

[Ben Coulthard]

Go vertical. It's the future!

Higher temps. Usually causes by cut airflow due to being so close to the door/window
