Hi everyone

I`d like to know if still worth making a Crossfire between two 6870.

I have one for a year I can run everything fine, but Guild Wars 2 get on my nerves being heavir than Battlefield 3.

I can max settings it with 35-50 FPS.

And really high temps. max at 79C. (Guild Wars 2 = Furmark? lol)

I can run Battlefield 3 max (Less XXAA) around 40-55 FPS

And max temp at 73C.

My System:

3570k @ 4.0
16 corsair 1600
Crucial M4 128
GA-Z77X-UD5H

Thank you.

79°C is normal for GPU under load so no worries. I prefer a single more powerful card but if you pick up another HD6870 for CF there is nothing wrong with that.

Best solution

I agree. Temps aren't anything to worry about. When you start pushing 90c, that's when you should consider cranking the fans up or something. GPU's tend to be more tolerant of high temps than CPU's. While I'd also prefer a more powerful single-card, a second 6870 would a much better upgrade. I'm all for the second 6870.

if you already have the first 6870 the second one is the best option you have

I do rather buy something like a 7950 for $320 or a 660 Ti for $300 because I am not a fan of crossfire configuration. But there is nothing wrong when you want to crossfire your 6870. But just make sure you give your case a good airflow to put temps down below 80C, and just make sure you have a good PSU with 4 PCI-E pin connectors (to give the cards the supplementary power.

It's pretty hard not to like Crossfire, especially for the 6800 series. They scale almost linearly (something like 95%). And 3-way Crossfire almost eliminates any Micro-stuttering.

What about CF between 6870 and 6850 does it worth?

About the power, I have a Seasonic S12II 620

Sell it on ebay for $150 and get a GTX 660Ti or HD 7950.

the 620 seasonic will be enough for 6870 CF

There would be no performance difference between 2x6870CF or 6870+6850CF since it will work on the specs of the lower card. 6870 deserve the extra money
