I'd expect your CPU to bottleneck with 6850 CF, I heard many people say FX processors doesn't have good crossfire support.

6850 CFX is more powerful regards to raw performance.
What settings do you play at?
What model PSU?

+1 to CPU bottlenecking.

6850 CFX won't do much for BF3 mated with the FX 4100. BF3 has been seen to be a demanding game for CPU and GPU. If you overclock the FX 4100, you may alleviate some of this issue, but be prepared for high power draw and plenty more heat.

What resolution do you play at?

Good luck!

Under "Performance" there exists Graphics Overdrive, CPU Overdrive, and AMD Overdrive. I would recommend leaving these be and overclocking in the BIOS if you can. MSI Afterburner or Sapphire TRIXX can be used to overclock in OS, unless you are inclined to flash the GPUs for retention of settings, if nothing else. Flashing to 6870 bios will NOT unlock extra the 160 SPUs on 6870s.

These cards are generally capable of about 900 MHz core, 1150 MHz on the memory at the high end, just be sure to watch temperatures. Mine run 24/7 at these speeds at 95-100% utilization (BOINC), sticking at 64 degrees C, 22 degrees C ambient. Fan speed I flashed to constant 70%, right where it just starts to get audibly noticeable.

Drop that PSU quick, and go with what recon-uk suggests. 80 Plus Bronze. Check. Single Rail. Check. Modular PSUs are a very nice feature. I have a Seasonic X650, pretty sure some of Corsair's products are Seasonics inside.

I'd try overclocking the FX 4100 first to see if BF3 shapes up. Then try inching up the 6850s. If all else fails, an Intel i3 2100 or an Intel i5 2500K and a new (at least PCI-e x16,x8) LGA 1155 motherboard with 2 slot spacing in between the 6850s is about all I can recommend in all confidence. Wait for a week or so though, and let Ivy Bridge shake up the market. Might mean better prices across the board.

I'm pretty sure an FX 8120 would not perform much better. A Phenom II X4 or X6 might.

As to your BF3 performance. Is the problem a stuttering of sorts or just that on higher settings the game is unplayable? I've seen a single 6850 with an I3 2100 perform higher than medium.


And as an aside: is this a pre-built PC? If so how long ago did you get it? The thought of returning it, and building something better in the same budget with your extra 6850 could be possible. Its just that AMD's newest FX processors are really not great for gaming (on the mid-high end that is), and that Hantol PSU is a time-bomb.
