First of, gaming just does not have the potential for parallel computation. Please don't say future games will all make use of 4 threads or more. It simply isn't possible with the nature of the gaming (and the fact that they are console port). Few will but most will not.

Actually if you use GPU for GPGPU related task PCIe 3.0 will be advantageous (people love to think GPU is for gaming purely). Given how AMD is pursuing HSA, this is critical to them. Intel is doing the opposite just so you know (making CPU as flexible as it can be).

And yes, AMD will be brining SoC design sooner than you think,

If Kaveri will be using SoC, then it makes little sense to reuse AM3+. Keep in mind that each time AMD decides to retain backward compatibility it will cost them money and performance. To bring DDR4, PCIe 3.0, and SoC design it is critical that AMD invents a new socket.

all true, but you are missing something. full gpu-cpu intagration isnt supposed to happen till after excavator, and while apus are amds main focus they are still makeing am3+ versions. look at trinity. what is trinity? pildriver with a gpu on die. thats how it will be till at least the end of steamroller, an apu using the piledriver/steamroller cores + gpu, and a cpu using just the piledriver/stearoller cores. ddr4 and and pci 3.0 will be addd in the 1000 series chipsets, using the am3+ socket, as amd added ddr3 in the am3 socket. amd said in there 2012 fiscle thing that an undated pildriver (aka steamroller) would come to am3+ shortly after the same cores came to there apu line. full soc wont happen till after 2014. thou theyve been quite about excavator, we can say there is a good chance it will use steamrollers am3+ socket and 1000 series chipsets, with ddr4 and pci 3.0. after that both apus and cpus are yes to be replaced by socs, same as with intel .(brodwell)

those socs on the thing there are replacomg the c, e and maybe a series, not the fx series. also gaming can be more pallerel, look at bf3- up to six cores used very well. also, as you yourself said, its not all gaming. other things will use more cores even faster then gaming will. consols will get more threads too. there only using three threads now just cause there 5 years old! so the consol port argument more for less then four cores dosnt hold water.

For 1000 series chipset to have PCIe 3.0, it needs to use a faster proprietary connection (similar to Intel QPI) that replaces HyperTransport 3.0 (assuming AM3+ backward compatibility must be retain). Memory controller is inside the CPU, has nothing to do with the chipset (though a new socket is needed to rewire pins).

While BF3 does make use of 6 threads, due to Amdahl's law (and the fact that gaming has little parallel potential in the beginning) it offers little to no performance gain against a quad core CPU. This is evident when you look at BF3 multi-player benchmark. Make no mistake that extra core will be useful, but that does not mean dual core CPU is outdated. Even in encoding i3-2100 evenly matches against an OC'd 960T.

ah yes, but does it beat an unlocked 960t x6? i think not.

completely off-topic but you have a (somewhat official looking) online bf3 benchmark source? I would love a link.

he could fit an i5 for $300: 4gb ram stick, cheap z68/p67 board and a i5 2500k all new for around $312. :http://pcpartpicker.com/p/a0Hr
