Quadfire with i7 4790k?

[MLG JFK]

Okay so before i begin, yes i know the r9 295x2 is dated and that the 1070 rivals it in all games. However, i already own one.

        My friend is offering me one which he barley used for 280 dollars. My question though however is will 2 r9 295x2's work with the i7 4790k?

             I know it only has 16 pcie lanes, but Ive heard amd cards can run in 4x mode, and I was also unsure if since technically only 2 pcie lanes were being physically filled that both 295x2's would run in 8x mode or what. So will it work or nah? Also my cpu is oced to 4.8ghz so i dont think there'll be a bottleneck there.

I also have a 1600 watt psu so no power troubles.

the should in theory be 8x 8x otherwise it will run 4x 4x 4x 4x which is still fine

It should basicly work, because those cards have their own plx chip onboard.

it should work , and they would run in 8x /8x . however , do consider the heat.
