Hi Matthias :-)
Maybe it's better to install a cooling on them?
That could be one solution. The 1.3 cards are known to have heat problems.
Would it be an option to buy a budget card? If I understood it correctly the budget card has no TV output but that isn't necessary if I have one FF card or?
Thats an option. You only need one FF card to do the video-output and so on. I've also One FF and one budget card and that works really fine.
Or are there any other drawbacks?
I don't know any drawbacks, but maybe others know some?
