[INSIGHT] GTX 670 3-way SLi v. Radeon 79xx 3-way CFx - Page 3

You also start to get diminishing returns once you get more than two cards. I would get two cards, and then if you aren't happy with the performance grab a third.

Go with two 7950's, best bang for your buck. And get GOOD miniDP adapters, I can't tell you how frustrated I was trying to run eyefinity with the cheap $30 ones, I have 6 or 7 bad ones still floating around my closet. If you do the math I could have almost afforded an extra GPU for the price of those. Three cards is a waste for your needs, it will sit idle more often than not.

I read somewhere that a 3-card-setup (AMD or Nvidia) eleminates micro-stutter to zero......is it true?

With AFR, yes. It is still possible to have MS but significantly less likely. I wouldn't worry about MS, I've had dozens of dual, tri and quad GPU setups and I have only seen it once since the HD4000 days and that was with GTX 670 SLI that had a bad card and I ended up RMA'ing it.

id say go with 2 7970's and see what you need from there. Also to the post that state his cpu will bottle neck there wrong. There are a few members who are running tri 7970's on amd with full 100% gpu usage without any issues.

I understand AMD is better priced. But I have been plagued with driver issues with my 3 7970's. I would rather go back spend more money on Nvidia. At less I would be able to game on games at release with all my GPU power. I'm still waiting for fixes for 7970's and its been lots of waiting all year one problem after another I been waiting for fixes for.

Out of those choices I would grab the nvidia option purely because I don't like XFX....

that being said, you should be grabbing a 7970/7950 from a better brand/card

670 FTWs clock great though but 7970s will net you higher FPS.

What OS and video editing software are you using, have you made sure that the video editing software will take advantage of multiple cards, is that why you're wanting more than one gpu??

Just some things to think about, I could give more info but don't have enough details.
