Ya! it wil work with 100% efficiency......

because "Radeon R9 270x" supports PCI-E version 3.0(bandwidth 1 GB/s Supports Clock speed upto 8GHz) ........PCI-E 2.0 x16 (bandwidth 8000 MB/s and Supports Clock speed upto 5GHz) '

but ur Graphic card has Clock speed 1.05GHz ......so, it is compatible wit 2.0 x16 and runs wit 100% efficiency
