Is it Possible to run a Graphics Card in PCI-E 4x Speeds?

After a while, I finally went out and got a desktop computer. It has a quad core AMD Kabini processor, so the architecture isn't that old. The onboard graphics on this APU are much lower than mediocre. The first thing I did when I got this computer was to check the motherboard to see if it came with a PCI-Express 16x slot, which it didn't; it came with a 4x slot instead(stupid ITX boards). I would definitely take the extrea performance you would get out of a graphics card over RAM, so I decided to get a graphics card. Online, they have PCI-E 4x to 16x adapters/risers. I know there will be a loss in performance, which is the reason I'm only getting a Radeon R7-260x 2gb. I'm fairly confident in my ghetto-mounting skills and how I won't get it to sag on a flexible adapter card, the only thing I'm concerned about is power delivery. Will it still deliver the same amount of power through the riser card as it would normally? This graphics card DOES include a molex to VGA 6 pin so I'm not worried external power wise. My only concern is the power it delivers through the slot, and if it would even work. Thanks in advance ;P
 
Solution
Yes, it will work. PCPER did an article quite a while back in which they showed that a low-power Kabini along with a GTX750Ti was a competent gamer (with lowered settings).

Thanks for the answer! I was expecting another answer that talks riddles, but I feel like a 260x will be good. I might upgrade to a i5/fx once I get more money, but I bet still not being able to run games at ultra would be much better than me doing Call of Duty at 800x600 on lowest settings @35 fps. :D

In fact, I just found the article you were talking about, that's the processor that I have. Thanks again for clearing things up.
