Most of the time you should be fine if your CPU is running at ~3.9Ghz

My amd proc was choking the 6870 setup I had. I would get around 55-60 fps in some game while the same setup with an i7 would get 75-80. Most scenarios you will be fine but in some you will be held back.

I have a very similar setup. With the DX9 pipeline, I often end up close to be bottlenecked because one core nears 100%.

As an example, I am severely CPU-bound in the original crysis.

In most recent games as well as in most benchmarks where GPUs are very solicited, I got no problem in 1080p with 4XAA

It will also depend on your resolution. Higher resolution and AA will load the cards more and the framerate cap will be determined by the GPUs. I play in 1080p.

By the way, Crossfire is a bit of a mess. Drivers are not quick enough to follow patches and most games are released with multiple graphics update. Therefore, you often end up with broken or semi-broken CFX.

Also consider you'll have 1 GB of video memory, not 2. This is starting to be low but should not hinder 2011 game performance. Crysis 2 works better with a bit more. This should not be a showstopper but something to be considered nonetheless.

This has been my experience as well.

By the way, DX11 titles are not as demanding when is comes to the CPU rendering capability. Unfortunately, multi-threading, which would be a must for Hexa-owners is not yet supported properly by the drivers. BF3 will not use it.
