Some FX 8 Core are supported, namely the FX 8100 (Which i didn't know even existed) and the FX 8120.
However no Vishera CPU's are supported as of now, so just to be sure, go in a PC shop and ask someone to test if your motherboard supports Vishera CPU's.
And if it does, i strongly reccomend you buy either a 6 or a 8 core.
Dang, well, right now I have an X4 975 with a stable oc of 4.0. I am planning to get a 7970 Lightning, and I didnt want my cpu to be a bottleneck when I play games. Basically I want o get the best gaming experience possible, will my current cpu be an issue?
Otherwise, Ill have to get a new motherboard as well as the new cpu, and I cant afford that and the Lightning.
If you have a PhII X4 @ 4.0, don't bother swapping cpus. Bulldozer chips are slower performance than PhII and the Vishera chips are only slightly better. Clock for clock your PhII is actually probably a little faster. Just get the GPU and be happy with it.
I know my 890fx crosshair IV takes fx 8350 and can overclock without a problem, and asus says it only supports the 8150 with the bios update. I would say it wouldnt be bad to try as the cpu can be returned, but its weird that ur board only supports the 95w am3+ cpus.
I read that with bio update 1.6 it gave support for bulldozer, and 1.7 seems like beta which just came out may give u the piledriver support, as it shows modify cpu code
If u could get piledriver i would def got 6300 over the 4300 its only $10 more and if u can the 8350 as it'll beat out the phenom II line
