When this machine does croak I will build a new one myself which is (like you)
what I used to do years ago.
I don't understand. Compared to a single core, four cores gave:
[much (usable?) goodness]
This is the CPU I run today... an AMD A8-5500... a 4 core processor running at 3.2 GHz.
<http://www.newegg.com/Product/Product.aspx?Item=N82E16819113288> Its single thread performance is about 1/2 that of
the fastest Intel i7 and its multi-thread performance is not much better than 1/4 of the Intel. On the other hand,
those adjustments I make in ACR or single image adjustments I make in PS (levels, brightness/contrast, etc.) seem
nearly instantaneous. So, how fast is 3 or 4 times instantaneous? It's a non-interesting number. But building a 10
image panorama is a horse of a different color. I don't know what a significantly faster CPU might do for me there.
But neither do I build 10 image panos every day.
These days, I'm stacking, aligning and merging focus stacks of 12 or more files fairly regularly. When I've been on a
trip, I often have several multi image panoramas to merge.
My work flow may be unnecessarily complex for most folks. In any case, I often end up downsampling multi layer images,
adding FM, often masked, as needed to compensate for loss of detail to sampling, etc., then saving as JPEGs. I used
Genuine Fractals (now more bloated and less useful as Perfect Resize for 64 bit), based on better results than the then
PS downsampling. Recently frustrated with PR failings, I tried the PS function again. It seems much improved in results
- now at least as good as PR - AND, it's much faster than PR, "nearly instantaneous", as you put it, with only a handful
of layers. I imagine this improvement in speed and results may be a result of recoding for multi-threading.(?)
The price difference between middle of the road and just short of bleeding edge performance is so slight that I can't
see the point of scrimping. I spend so much time at the computer working with images that making it slower in any way
makes no sense to me. A faster machine also ages better, as hardware gets faster and image/video applications more
demanding.
