Yeah Ivy Bridge for quad fire....

Great article here on AnandTech about the subject.....smile.gif

Interesting thread, so its saying a 3770k or 3930K is needed for quad 7970 setup. I cant understand why they say the 2600k wouldnt be sufficient though.

Good to know I wont need to upgrade my 3770k for many years then.

For gaming the 3820 is fine. I think tsm has a write up somewhere about it since he did the switch from 3820 to 3930

That's because they tested it at stock, so the 3770k is going to have the edge there with it's increased ipc

I don't know if I would necessarily agree with their conclusion though, for the price the 3770k is certainly a beast and hard to fight against but I just don't think I would ever recommend a PLX chip over native bandwidth

Thread Starter 
i thought since the 3820 had 40 PCI-E lanes that it was made for Quad GPU setups, and wouldn't be affected by multi-gpu from my understanding (i thought).

Too much theory crafting here.

Here's a chart for tri-fiire, I think they didn't do quad-fire for whatever reason


http://www.anandtech.com/show/6934/choosing-a-gaming-cpu-single-multigpu-at-1440p/5

Pretty bad scaling to quad


If you're gaming I'd go with SLI GTX 780 or Tri-SLI 780 if you want to blow cash

How about i7 - 3770k + GTX 780 sli oder trislie? Its cheaper than Titans but not really slower.

Or I think you will be fine with the 8350 and 2 Gtx 780 for gaming. Just do some custom waterloop and oc it like crazy biggrin.gif

Edit: meh Alpha already mentioned the 780s rolleyes.gif

After seeing those graphs I would go for the 3770k and a decent Z77 mobo OP, the UD3H is a good start tongue.gif

No need to go SB-E I dont think. The 3930K is getting close to double the price of the 3770k.

How is that a good start if it can't even support the GPUs?

On the charts the 3770k is almost identically performing the same as the six core SB-e cpu in quad 7970 setups?

Unless im missing something and your referring to mobo features, im not familiar with the necessary components for quad GPU setup I only ever used single gpu.

He meant the board.

Clearly not made for quad GPU set up unless he's dual Titans
