I'm upgrading from - to:

LENOVO SHARKBAY (SOCKET 0) - GIGABYTE B85M-D2V
Some 300W idk... - be quiet! SYSTEM POWER B8 | 550W bulk
GeForce GTX 745 2gb MSI - Gigabyte GeForce GTX 1070 Mini ITX OC
Typical Lenovo h50-50 case - Zalman T3 Mini Tower (with 4 fans)
8GB DDR3 1600 MHZ RAM - Remains
I7 4790 3.60GHz - Remains

Every component comes from LENOVO H50-50 90B60046BG

LENOVO SHARKBAY (SOCKET 0)
GeForce GTX 745 2gb MSI
I7 4790 3.60GHz
8GB DDR3 1600 MHZ RAM
Western Digital WDC WD10EZEX-08M2NA0 1TB
HL-DT-ST DVD-RAM GHC0N

So someone told me that the CPU is OEM for some of the H50-50 builds and it can't run with other motherboards.

So the questions:
Is that true for the OEM CPU
Is there something that doesn't run good with something else?
Am I gonna get bottle necking and random stuff like that, that reduce the performance?
