Adding to this, some time back I read an article from a programmer about how difficult it was to make a program truly multi threaded, without going into detail you can make a one threaded program quite (in their skill levels) easily, going to two core was double the difficulty and dual threaded, but doable, after that it became extremely hard work in a sort of Universe expanding size to keep up.
I think there is a reason Intel have stayed at 4 cores for now (apart from the 6 core XEONS for a select small market) They know the market and knew AMD could not pull this off, even their projected market of Ivy Bridge will stretch to 6 cores as a max for 2012 as well. AMD going for the first 8 core joe smuchk CPU dirt cheap seems like a bad idea in the long run ... IMHO. Small steps AMD, not big lunges.

 ) with just DOS 6/5 working on it ... I could have retro went a PC with a DX2 66 CPU, but looking back I've got best chance of this retro idea working with a P200, its got 32 MB of ram that was absolutely massive at the time and last time I fired it up it worked.I'll dig it out again and if their is any interest I'll do a thread about old retro PC flight sim. I hang on to almost all my old gear, hear is a pic of my current HOTAS collection ... I've given away my Saitek X-52 pro, but in the background you will see my old Thrustmaster F22 pro and TQS for DOS purposes I hope to get working again one day

Pretty disappointing from AMD.
On the other hand it's never been good to go out and buy anything right after release. For my part I have to say if the next itteration from AMD (let's also see what happens with the new FM2 socket) is not significantly better I will most certainly go to Sandybridge/Ivybridge, depending on availability and pricing when I need a new mobo+cpu. I have been looking forward to the Bulldozer but I won't put any money up for it or a new 990fx mobo, as of now it's not worth the price of admission and sadly, since I always valued AMD's approach to socket/cpu flexibility, an i5 2500k is starting to look really good. Btw, my first pc after my amiga was a 486 with a whopping 4mb of ram....ahhhh pacific fighters.....

I just read the tomshardware.com review of the AMD FX-8150.
It's pretty disappointing considering it was supposed to beat Sandy Bridge  Now Intel can charge whatever $$$ they want for SB because AMD has no high end chips for competition.

Not much into throwing stuff myself either... Still have my Spectrum and 286 in the cellar. Fired them both up last year in a cloud of dust. The speccy worked nice but the image was a bit jagged on a large flat screen tv  The problem with getting the 286 to run was to find the 5 ¼ inch disks with something to run. The 20 Mb hard drive just had DOS 3.22 Mazex

I haven't read the reviews yet. but this is what I was afraid of. I was really trying to hold out for Bulldozer, I wanted to believe that AMD could be competitive and maybe superior to Intel's offerings.
But the continual delays and generally bad vibe I was picking up about Bulldozer made me go with Intel, and I feel sorry for those of you who held out for Bulldozer only to find that a good old 2500k/2600k was there to be bought all along. The problem for AMD is that Sandy Bridge-E and Ivy Bridge are on the horizon. Bulldozer really needs serious stepping to make a challenge. On the other hand, if AMD can offer a great price/performance ratio as they have done in the past, then they can still be reasonably competitive with Intel, just not in the absolute performance stakes.

Just to add, the problem with multithreading is that for games, four cores is as much as you'll ever need for the next two, maybe three years. Maybe even longer.
There are some games that apparently run a tad better utilising six cores, but the vast majority don't need more than four to run as smooth as silk. Eight cores? Only if you're heavily into certain mutlithreaded applications (ie. not games) will six cores or more make a difference. For games, it''s basically a waste of time...this is especially true since more than half of PC games are mutliplatform games, meaning that they're also developed with the ancient console architecture in mind. No developer with half a brain is going to specially bring out a special PC version of that game; it's too costly for very little return. And no game developer at present is going to optimise a game to use eight cores, much for the same reason. In about 2014 I'll look around for a replacement for my 2500k, but for the next few years, aside from a GPU upgrade, I'm not spending another cent on my machine.

My biggest disappointment with Zambezi was seeing how poor the single thread performance is, especially compared to the previous generation (Deneb/Thuban) chips. I can accept that the multi-threading capability is a bit ahead of its time, but it’s unacceptable that a new cpu will not perform as well as the ones it replaces in the majority of current (single-threaded) desktop applications. I also do not see how this can be improved without a major re-design of the architecture – the predicted 15% improvement with the next iteration (PileDriver) is still somewhat short of what it needs to be

Maybe AMD will come back with their Forklifttruck chipset next? Whoever thinks up their silly macho chipset names needs to be sacked.
