Yes they are compatible ,just make sure to get a good compatible motherboard.
Before I hit buy is this Mobo gonna be good. Everything sees to check out but wanna be sure u know. GIGABYTE GA-990FXA-UD3 AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard. Sorry if I'm asking stupid questions is just that this is gonna be my first build and I just barely started learning all of this stuff.
