ok please read this carefully so you dont make the mistake i did, nothingn too big but sorts allot of *** out in the future
basically am3+ will work with all AM3 cpus, as well as AM4 CPUS, or am3+ cpus, so its good to get it for fure compatibility
But before you buy the build, please check if your ram is certified by your mobo company. For example i bought an msi 870a g54, and the ram wasnt compatible with the mobo, and so i had to return it, i bought another ram from the list that was given from the motherboards page and im awaiting the delivery of it.
But yeah you should really check to see if your parts are compatible with the mobo. Im not just talking about ddr3 1333 mhz stuff though. Two of the identical basic specification ram, one may not work because the advanced specifications may be different.
I dunno too much about that but yeah, deifnately if there is a list of rams that are compatible with your mobo, check that list out please.
If not, get a good brand one like gskill or corsair, kingston (not value, well i was not reccomended to buy value ram but its not that bad).
Just make sure your ram is not generic, i made the mistake of buying real cheap ram that was generic.
also do a memtest86+ test on your ram afterwards. If you get alot of errors you may get BSOD's in the future.
Also about the phenom x6 cpu, imo if your going to be doing alot of multitasking then yes x6 is fine, but if youre getting it for gaming, just go with a 955 x4, or a 965 if you really want some performance cheap.
