Amd 970 chipset for crossfire

[deception]

I have a 290x and plan on buying a new CPU and mobo. A 6300 with a gigabyte 970a-udp3-p.

What would the performance be if one day I wanted to buy another 290x to crossfire on this chipset? (unlikely but curious to the answer say vs the 990fx)

Crossfired 290x's would be bottlenecked terribly by a little Fx-6300. A single r9 290x is somewhat bottlenecked by a stock speed FX-6300. Yes, it'd all run on there. And yeah, the Gigabyte 970 udp3 is okay for a mild OC (990 is where it's really at), but it's by all means not an efficient setup. Upgrade the CPU to a 8320 and OC it, or go with a 8350.

It's a really bad idea to use AMD 970. 290X uses no bridge for crossfire and needs more PCI-E lanes. Buy a 990FX. It is not so expensive.

Not only would there be a cpu bottleneck, but from my understanding, practically all the 970 chipsets have the second pcie slot running at x4 if you crossfire and what not.

I'm more likely not going to ever crossfire, more curious, and I read on these forums it's not about the chipset for ocing.

That a gigabyte 970a-udp3-p will oc just the same as a gigabyte 990fx udp3.

Im going with a 6300 cause is $60 cheaper then the 8320 and Friday morning what I've researched I'm not going to see much of a leap in performance

To expand on what Calnin is saying, the 970 chipsets (most) have 2 pci-e slots; 1 at x16 and 1 at x4. Because of this, they aren't optimal for crossfire/SLI.

Both the 970 and 990 have 8+2 phase designs, so in theory, they'd have similar OC ability for the CPU, which you're going to need if you really do intend on running a FX-6300 to run alongside with a r9 290x. The 8320 has a couple more cores, but if you won't be streaming, gaming, recording, and doing other tasks all at once, the FX-6300 will be okay. Just OC it to about 4.5 ghz.

does it support crossfire?
i never see a good amd motherboard,
is this good for overclock?
can you prefer a best cpu for this motherboard?thx!!

Good overclocker and it supports SLI and Crossfire.
