Minimum Cpu needed for CF

[starravier]

whats the minimum processor needed to run Crossfire with 2x6870's or 6850's both AMD and Intel

There is no minimum(or maximum for that matter) processor for crossfire or SLI. Any processor will do it. If you are asking for minimum bottleneck on stock clocks then it will be the Phenom II X4 980 from AMD and i5 2500K from Intel. The Intel solution will be faster among the two. If you are willing to overclock then the Phenom II X4 955 gets the recommendation from AMD camp.

well i was thinking of getting a AMD X4 975 or the X6 1100T but is it worth getting CF if im just using one monitor?

Crossfire isn't about using multiple monitors (that's Eyefinity), it's about using multiple GPUs to get extra graphics processing power.

Well that answers that, now which processor?

That is your choice all the CPUs you have mentioned will happily run Crossfire 6870 without a bottle kneck, now its just down to your budget, AMD being the cheaper option, personaly i would buy a 1090T a decent aftermarket cooler and OC your CPU to 3.8 - 4.0ghz.

PS, what resolutions do you game at ?

1600x1200

The i5-2500k even if left at stock clocks will likely outframe the X4/X6 based rigs even if successfully OC'd to 4 GHz...; if the $100 more in CPU cost (over an X4 955)is not a prohibiting factor, the i5-2500k is the obvious choice in my opinion....

 

[Emperus]

You don't need a 6870 crossfire for that resolution. Better to get a single more powerful card instead.

I agree^ with Emperus.
