Hello,
I wanna build a new system, and i am lost in options for 10 days now .....
Let me get what i like and what i dont like first:
1 - i am an AMD lover and intel hater
2 - i use AMD cpus since duron 700
3 - i use ATI card since radeon 7000 and radeon 7200 ....

I was gonna build my new system like this:
cpu: FX-8350
M/b: asus crosshair -v formula-z
Ram: vengence 16gb
Vga: 2 x amd radeon r9 290x
And etc
But i just got thatt alll amd mbs are pcie2 while intel ones are pcie3

So a friendmof mine suggested to buy this pc:
Cpu: i7-4770k
Ram: same
Mb: msi z87 xpower
Vga: 1 x gtx780ti

But i donot want intel pc .....
Here is my question :
Which vga is more ppwerfull and how much higher do 2x290x will be than a gtx780ti?!
How much performance will i lose (on vga) if i go with pcie 2 motherboard

Hey there, I think your question should be more to the difference between the 2x 290x and 2x GTX 780 ti performance wide, both of those cards are PCI-e 3.0 and therefore that would not become a problem.

The problem, up until this point the only AMD-compatible Motherboard that has a PCI-e 3.0 slot is the ASUS Sabertooth 990FX/Gen3 Rev2.0, none other has a 3.0 PCI-e on it, also, that shouldn't become a problem if you are not trying to get the best of the best out of it, since the performance difference should be around 2%~3% (source - http://www.tomshardware.com/answers/id-1689846/pci-pci.html
