is the r9 270x able to be run on pcie 2.0?

[huthman]

I just bought a xfx radeon r9 270x. after buying it i recognized that it needs(?) or has got pcie 3.0. I already looked in other fora but some say "yes its compatible" and some say "no its not". additional to that some say that its a big power loss to run it with pcie 2.0. now i ask u:
Is the radeon r9 270x able to be run on pcie 2.0
and if yes
Is it efficient or should i better buy additional to that a new mainboard
and if that is also true
is there a mainboard whith pcie 3.0 AND am3+ socket
if u know one pls add it to your post

Sincerely,
Huthman

Here is your answer: http://www.tomshardware.com/answers/id-1876259/amd-270x-pci-mobo.html

This is taken from Truckinupga: The speed difference for 2.0 and 3.0 is almost completely non existent. The 2.0 bandwidth for PCI express hasn't even been saturated yet. So go for it, you'll loose nothing by having only a 2.0 PCI lane. And any GPU that is PCI 3.0 is backwards compatible.

Your 270 (7850) will run the same is bout 2.0 and 3.0 as mjmacka said.

Thank u all for your previous answers. Im sorry that i didnt looked at the forum before, so that i didnt recognized that there was a post like this before. now i stand in front of another problem...

i built the card onto my board (also added the extra power cables), started the pc but the screen stayed black. i switched the dvi port (it has got 2) but there was still no reaction of my screen. because of this missing reaction i shut the pc down whith the power button (1 short press) and it went out nearto instantly (so i think my pc didnt boot).
im glad about any problemsolving answer

A BIOS update solved the problem...
