Is my motherboard compatible with this cpu and gpu?

[llaime]

Hello,
i want to renovate my PC and i have a P7P55 LX motherboard with a 2x2Gb DDR3 ram and a intel i7-860. I have a Tacens power supply too(i dont know how many w have). I want to buy 4gb Ram ddr3 more and i want to buy a GPU like a geforce 960 or R9 270X. Some knows if i have some problems with the other components or some incompatibility?
Thanks.

The motherboard supports up to 16gb of ram. So yes, you can add more memory.

Both of those graphics cards require a pci express x16 slot, which you motherboard has. So good to go on the graphics card.

As long as the psu is 400w+ you should be ok power-wise.
