It all depends on what kind of image analysis is prevalent in your facility, and what is the largest file (image data set) you are working with (deconvolution, 3D/4D image analysis).
Workstation is what you need. You can get the right one from Dell of HP outlet, the rest could be added (LSI RAID controller/HBA, RAM, graphics, etc). You may need dual processor if you use Parallel Computing TB.

If you need more specifics, please contact me offline.

Dear listers/microscopists,

I assume there is good time to update new trends in
image analysis hardware. The last discussions on image
analysis computer were in 2006-8. Though the basic
principles of CPU, RAM, hard drive, video card, monitor
selection still hold some new types of hardware became
popular/available, e.g. SSD drives, APU, water cooling.
Now a decent gaming computer (~$1k) has the processing power
of a 2006 expensive workstation (~$20K). I was suprised that
I was able to completely overhaul my 8 year old ATX case
to a quad core 2GHz APU, 8GB 1600MHz RAM, 160GB SATA-2
SSD, water cooling, USB3 and SATA3 Gigabyte motherboard,
and 4 monitor 1GB video card.
for under $300 (online, after rebates).

Now I am wiling to upgrade/overhaul my work computer which
is used to run ImageJ, Fiji, Deconvolution (Autoquant, Huygens),
Matlab, PV-Vawe, Labview, Origin. Please advice/share you thoughts
what best configuration is possible to buy for $2-3k (monitor
excluded).
My first choice would be  to go with a fast gaming computer, e.g.
Dell-Alienware Aurora 
Windows* 7 Ultimate, 64Bit, English
2nd Generation Intel* Core* i7-3820 (10M Cache, Overclocked up to 4.1
GHz)
16GB (4 X 4GB) Quad Channel DDR3 at 1600MHz
NVIDIA* GeForce* GTX 660 1.5GB GDDR5
1TB RAID 0 (2x 500GB SATA 6Gb/s) Solid State Hybrid
19-in-1 Media Card Reader
No Monitor
Integrated 7.1 Channel Audio

The second  choice would be to buy all components online and
build a computer myself (I have done this about 50 times over
25 years). This option typically saves money or buys better
components,
and provides you full specs of the hardware. The con of this
approach is that it wastes some of your time to debug/make all
the hardware work together and with your software. However,
as the computer is for me not just a box but a tool I am ready
to make this sacrifice.

BTW, is there any solid preference towards CPU Type (Intel ix/AMD/Intel
Xeon)

Thanks for your input/advice/thoughts,
Arvydas

Hi Chris, 

Agreed about FRET with a dichroic-based beam splitter on the emission
side such as a DualView or QuadView.  No commercial interest, but our
group uses a DV2 widefield/TIRF system for quantitative FRET just about
all day every day.  As the executives say, drive for show and putt for
dough.  In general I'd always go widefield if quantitative is more
important than spatial.  

JP, unless I remember wrong the 510 has its detectors in a series with
switchable dichroic filters between each detector (for example, a
515-ish nm longpass dichroic between detectors 1 and 2 if you want to
see cerulean/venus/FRET).  Thus it collects each emission channel
simultaneously and can go as fast as it can scan a line and alternate
lasers, which pass through a two-notch excitation filter.  
Creulean-FRET bleed-through is still a bear of course, but it always is,
and there are long established ways to correct that.  

cheers, 


TF
