 |

I was wondering what processor you experienced builders would recommend
for a pc that's main purpose will be digital photo manipulation.No video
or gaming or anything like that.This would be my first pc build,but not
first electronic experience(spent years with CNC machine tools).I'm
getting a flood of conflicting advice by just searching willy-nilly.The
other question is should I stick to crt for monitor?Again I see alot
about color management being more consistent with crt.(have I been
reading bull**?)Hope to keep the whole package at $1200 or less.Any
advice is appreciated.

While I don't really trust Tomshardware to run the Photoshop test, here
is a chart of results. The Intel E6600 and the AMD Athlon64 X2 dual core
6000+ are in the same ballpark, performance wise, and cost around the
$230 mark. Both of those processors have dual cores. For Photoshop, there
are some (not all) filters that use both cores at the same time. A
well run Photoshop test, will separate the filters into those that use
a single core and those that use two cores, and run a batch of tests
with each. In the case of Tomshardware, I'm assuming they've selected
dual core filters for this test.

Since I have to make a choice at this point, the rest of this
post assumes an E6600 purchase choice. That doesn't affect the
DDR2 memory though.
There are a couple basic params you are paying for, on the memory.
The speed is one - DDR2-800 has higher bandwidth than DDR2-533. But
in dual channel mode, anything over DDR2-533 is more bandwidth than
the FSB can handle well (at 533, 533*2sticks*8bytes has the
same bandwidth as FSB1066*8bytes). So the benefit gained is in the couple
percent range, in application performance. (The faster memory comes
in handy for overclocking, and leaves a bit more room to optimize
if you raise the FSB a bit.)
Another parameter is the latency from request until the data phase,
and that is CAS. CAS4 is less delay than CAS5. And the units are
clock cycles, so CAS4 at DDR2-800 is less delay than waiting
CAS4 at DDR2-533.
the video cards and power supply would eat more of the budget.

Wow,thanks for the effort involved in your answer.The Intel/Amd question
is one of the toss-up questions I'm considering but didn't think of the
memory in the way you described.I'm not using the full blown Photoshop
yet,but do want this system Photoshop capable.(using Paint Shop
pro,Gimp,Lightzone).Again thanks for the effort and I'll be sure to come
back for more questions as I make some decisions.
