Hi all, I'm in the process of upgrading my computer system. I build my own computers, and my next build is either going to be a AMD Phenom II X4 or X6 Black Edition.
Just curious if anybody out there has gone the X6 route and seen any significant improvements over 2-4 cores? Everything I read online says while Photoshop can use multi-threading, it won't use all 6 cores. Only exception are some filters (motion blur etc) that I almost never use.
Anyone with first hand experience?

I can tell you that on an Intel i7 2600k (four physical cores with hyperthreading, so eight virtual cores) Ps seems to utilize all four of the physical cores to a significant degree, but does not "split" its tasks to take advantage of the virtual cores.
This is during a panorama stitch of 10 5D images.

| So no real value of 6/8 cores over 4....yet? |

| In testing, Photoshop apparently maxes out at 5 cores. Bear in mind that future PS releases may be optimized to take advantage of new processor designs. |

It's also important to remember that just because Photoshop itself might be limited to the number of cores it sees or uses at the moment, it doesn't mean that 8 cores is overkill. Photoshop will still benefit indirectly by the extra number of cores because other OS/system/App based processes and threads can be distributed more evenly across the extra cores allowing more headroom on the cores that Photoshop is using.
So instead of Photoshop fighting for core processing time on 4 cores, the processing time can be removed from the cores it is using and assigned to the "extra" cores.
Of course it's dependent on your particular hardware capabilities, but 32 bit versions of Windows 7 can see up to 32 cores, and 64 bit versions can see up to 256. Not being a Mac user I can't really speak for OS X and related hardware.

I think I need an upgrade as well.
On this "Demotivational" shot I had about 87 layers in PhotoShop CS4. A dialog would pop up saying something about not enough RAM every time I selected something with the magic wand... Very aggravating! |

What are you running now OS and RAM wise. How fast is your current system...processor/core, 32 or 64 bit, how much video RAM do you have? It all helps obviously.
Have you tried giving Photoshop a little more system RAM to use under the performance properties in Photoshop? I normally keep mine between 60 to 70 percent because you have to make sure you leave enough for background and system services not to mention any other apps you want to launch. I know a lot of people who listen to music on their computers, have social network apps updating in the background such as Facebook and Twitter etc. I don't work that way. I try to give Photoshop and any other editing app I need as much of the resources as I can.
Also, most computers will have a problem with the lasso tool long before 87 layers. If you don't have your layers merged or flattened it has to apply your selection to every layer below and that takes up a ton of memory.

New computer system will be a complete overhaul:
AMD Phenom II X6 1100T Black Edition Deneb 3.3GHz Socket AM3 125W Quad-Core Desktop Processor
GIGABYTE GA-990FXA-UD3 AM3+ Motherboard
Western Digital Caviar Blue 320GB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive
G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory
Thermaltake Frio CPU cooler.
...and other bits and pieces.
Now just deciding on a video card.... |

The phrase, "get a life," comes to mind. I admire your commitment to your art. Best of luck! |
