will the Corsair CMZ8GX3M1A1600C9 Vengeance 8GB and the Sapphire AMD Radeon R7 260X be compatible with the Asus M5A78L-M USB3

just want to if the graphics card and ram are compatible with the motherboard

 

[CepheiA]

They are but:

Your PCIe 2.0 motherboard will bottle neck your PCIe 3.0 graphics card. Not by much, but it will.

You'll get better performance using a dual channel kit (2x4GB=8GB) instead of just using the 1x8GB ram stick.

what motherboard do you suggest in getting so the computer gets its maximum performance

 

[Tradesman1]

PCI-E 2 slot on the mobo won't even be noticible, the cards are backward compatible, on the DRAM be better with 2x4GB and would suggest the GSkill Snipers in 1600/9 1.5, dual channel can provide up to about a 10% performance gain
