Hi Marc, We were trying to build a modestly high end system with
limited resources. We just purchased 2, MSI nvidia GeForce 9600GT 700MHz -
512MB GDDR graphics cards from buy.com (no commercial interests) for
$158.00 each and we are running them in SLI mode on a Dell PrecisionT3400 quad
core with 4 GB RAM. If you have the budget you could go with the nvidia 9800
series. It is important to match the mother board with your graphics cards, all
new graphics cards are PCI express 16X, so make sure the motherboard has enough
PCI express slots. One more thing to note is the power supply, these graphics cards
are power-hogs and if you are adding third party graphics cards you will need to
change the power supply to a higher one. Also you will need to see if there is
sufficient spacing on the motherboard and between the PCI express slots to accommodate
these cards, they are big! Best, Neeraj. Neeraj

I owuld like to disagree with Craig. There are now quite a few programs that
use the graphics card to process 3D data in real time now. MetaMorph, Imaris,
Volocity, 3D Studio, Olympus FV1000, Leica LAS AF just to name a few. There is an enourmous ammount of choice out there in the
graphics card market, but my recomendation (and the recomendation of many other
people) is to buy the best GAMING card you can afford. While each graphics card
manuafacturer has "Workstation" class cards that cost a heap of
money, these cards oare not really any better than a good gaming card. So avoid
things like the Nvidia Quadro, ATI FirePro or Wildcat Studio type of cards. So you are going to need something like an Nvidia Geforce
280GTX or an ATI Radeon HD 4870. You will need at least 512MB of RAM on the
card as well. Also these cards cost in the order of $500-600 US dollars. Now slapping a highend card in a lower end computer is
not going to fix things either. To match the card you will need to have a good
CPU (dual coe is fine, there are very, very few programs coded for more than 2
cores currently) and the more system RAM the better. If you are playing with
large data sets (eg 2000 images per 3D stack) you will need to go beyond the
maximum 4GB of RAM in a 32 bit system and go for a 64Bit system and put 16 or
32 GB RAM into it. Fast hardrives will always help a little bit but not too
much. Also don't worry about going for a two graphics cards
running togther (Nvidia SLI or ATI CrossFire), as far as i know there are no
modeling programs out there yet that can leaverage both cards. Hope that helps you out, if you need any more help just
let me know.

uses your CPU rather than your GPU. The CPU does all the number crunching
then hands the resulting data off to the GPU (video card) to display it.
There are a handful of programs that will actually use the GPU instead, but
they are few and far between as they require special programming. What sort of processor, video card, and how much RAM do
you have in your computer? Craig On Wed, Aug 13, 2008 at 2:04 PM, Marc Thibault <[hidden email]> wrote: Search the CONFOCAL

Hi all, I would like to know what
are the best graphic cards to add in your PC for microscopic 3D image analysis
and manipulation. Mine is currently not up
to the task. Thanks Marc |
