People also tend to forget that their enthusiast level CPU is competing with mainstream Intel chips at well over double the power usage. In its current state, Bulldozer will not even be remotely useful/interesting as a mainstream option for OEMs or any other system builders/manufacturers, so your post makes no sense. The efficiency/power-per-watt of the current "enthusiast" BD chips has a direct impact on anything they will make with the same architecture/revision that's lower end, like it or not, it will still fail in those markets even more.

Example: 1055T (95W version) is probably the best power per watt CPU of the Phenom II series, since it runs 6 cores @2.8GHz + 6MB L3 cache (I think). Anything lower end is way less efficient per core/watt, like any Athlon/Sempron excluding their e-series versions, so my point still stands. No mainstream PC manufacturer like Dell will use it when they can use a cheaper Intel counterpart that will save them on PSU costs by using way less power at both idle & load and extend the lifespan of their PCs, thus saving them possible returns/warranty costs.

EDIT: server and the mainstream markets are where AMD makes their money. Their 16 core BD will flop big-time against their current Phenom II based 12 core Opteron, if current Bulldozer efficiency/performance is anything to go by and same goes for everything mainstream.

So let me ask this for anyone - mentioned in the article the use of GPU computations for much of what seems to cripple (not the best choice of words, but makes the point) BD performance, could something be written and implemented that would take advantage of a system running a BD and AMD video card, much like PhsyX (obviously different but similar) is handled by Nvidia?
you know, i think for the few games that do well on AMD (ie optimized/marketed for AMD) it could well happen...

No, it is not easy.

The code itself must be aware that there is a FP co-processor and be branch to take advantage of the it. Now, the developer has to worry about synchronization and coherency between the CPU and GPU. It is not trival.

However, AMD and Intel are openly working to make the hardware be more integrated (i.e. on-board IGP will eventually become multi-core general use FP units). On the software-side, there are libraries being developed/maturing to simplify usage.

They'll manage... they still have a great gpu line with a very promising future.

Are you asking about combining the CPU to do GPU work while gaming? I don't really think that is possible.

The CPU is a problem in games because it is bottlenecking the GPU; it doesn't have anything to do with the GPU and CPU having issues.

The performance of the FX-4170 is definitely enough to be a decent CPU for office and the likes.

No one does any heavy encoding and the likes on current APUs because the performance is not acceptable. Look at Intel Quicksync, it's a nice technology allowing you to transcode a video to your smartphone or iPod. AMD probably has similar goals, the difference being they would make it for transcoding, rendering, compression and so on...
The problem isn't that few people are doing it, the problem is it's expensive and unpractical to use a workstation.

What I want to see benchmarks on will be the server chips based upon the BD architecture. By the time those are released the clocks should be up and the chips should excel in a server based environment.

6 pages and no DOOM picture yet.

I'm pleasantly surprised.
