Pros: Works very well. No fuss. No need for an external power source.

Cons: Expensive

Pros: It works as advertised. I bought the card for my video editing workstation, knowing that the video card wasn't really as important if simply editing straight video without effects. Although I haven't tried in After Effects, I'm sure it will give me my money's worth there.

Cons: First, with this card the Elemental Accelerator plugin for Premiere Pro CS4 does not provide any advantage over the CPU when transcoding AVCHD footage into h.264 blu-ray.

Second, I can't be 100% sure but before installing EA Adobe CS4 was running perfectly stable. After installation, it has frozen up several times even after uninstalling CS4 and EA and reinstalling CS4 without EA.

Third, the transcoded footage produced by EA had some odd problems. It would ignore edit points so that with a two camera setup it would transcode the footage from both cameras. For example, I transcoded a wedding procession and when watching the finished product the groomsmen and bridesmaids would walk up the aisle from one camera view then they would walk up again from the other camera view instead of there being a cut between each camera view. It is really odd.

Other Thoughts: I ended up getting it without the Elemental Accelerator plugin for Premiere CS4 mainly because I wanted to try the trial version before buying it. That turned out to be a good decision as Elemental Accelerator has a number of issues.

Pros: Quiet, cool and very dependable. Installing the drivers in Linux was mostly painless. Haven't yet encountered any incompatibility issues using this card and running Maya 2010 on CentOS 5.3
The only time I have bogged this card down yet was with a 3+ million poly model with High Quality Rendering turned on, and it was still livable. Complex scenes and lighting that would have otherwise crashed my previous equipment are no problem for this card.

Cons: Not much. It was a little tricky to get the X Server settings configured but even a Linux newb like myself was able to overcome it handily.

Other Thoughts: Running this card in my "budget" workstation:
CentOS 5.3
Core I7 950
ASUS P6T Deluxe V2
12 GB Corsair DDR3
Corsair 750W PS
2x WD Caviar Black 640 GB in Raid 0
Quadro FX 1800

Currently running two displays with this card, one in 1920x1080 and the other in 1280x1024. Running two displays raised the core temperature compared to hooking up only one, but still not even halfway to the slowdown threshold.

It also came with the latest drivers pre-loaded from the factory.

Pros: I have 5 Dell 690's that were all equipped with the FX3450's. We recently upgraded the OS in these machines to Vista 64 so that we could run SolidWorks 2009 SP4.0 64bit. We experienced very bad video problems while working in SolidWorks. I tried every driver under the sun to fix the issue we were having with the FX3450's but had absolutely no luck. I bought a FX 1800 and put it in one of these machines and the problem has completely gone away. With the card being able to handle a lot more and the power consumption a lot less things seem to be more stable with SolidWorks as well. We are now going to replace all of them with the FX1800.

Cons: No Cons here.

Pros: Installation was a breeze with windows 7 x64, drivers were automatically detected and installed. Nvidia website also has the drivers for windows 7 available for download. This card, along with a core i7 and seagate 7200.12 harddrives is superior to my workstation machine running dual xeon processors (skt 771), a quadro FX 4500 gpu, and 15k RPM SAS harddrives. Solidworks 2009 x64 does not miss a beat even with full visualization on and real view graphics when opening a moderately complex assembly. This card is also 1/3 the cost of the FX 4500 when it was new years ago.
From every review on the internet it appears as if the quadro cards have drivers better optimized for CAD systems such as solidworks when compared to the FireGL equivalents. FireGL cards appear to be stronger in programs such as Maya.

Cons: People buying this card for the wrong applications then writing misleading reviews on newegg.
People comparing this card to gaming cards - apples to oranges. Even the most expensive gaming cards cannot compete with the openGL performance of the lower end workstation cards.
Price.

Other Thoughts: We built a computer specifically for solidworks 2009. Core i7 920, asus p6t deluxe, 3x 1TB 7200.12 seagate harddrives, 12gb G. Skill DDR3-1600 memory, corsair 750w power supply. Though windows 7 x64 is not officially supported by solidworks, 2009 appears to run very well and handles large assemblies well.
Depending on the application, one could probably get away with the much cheaper quadro FX 580 and still have excellent performance within solidworks.
Workstation cards are expensive; developer costs and support is what you pay for and its worth every penny. These cards do not sell at the same volumes as gaming cards so naturally they are more expensive.

Pros: The card works great with Maya, which is the primary reason why I bought it. Rendering and modeling are a breeze now. About the only thing that will slow it down is a heavy use of particles, like when using water effects. I am currently running it in my dell studio xps 435t and up till now no major hicups.

Cons: The price, but thats a given with workstations! The install was somewhat time consuming as solely installing the drivers didn't cut it. I had to manually change the bios to support the card. Also, not sure if this is the graphics card's fault, but after doing a quick render, the windows aero scheme will switch to visual basic (supposedly maya doesn't support it.) This creates some funky bugs when you have windows opened up within programs such as maya and photoshop, nothing major though (the model blinks until you close the window or until you move it to the side). But, the problem goes away when you shut down maya. So that could be vista or maya's fault.

Other Thoughts: I would have given it a 5 if the install was easier and if there were no bugs, even though the bugs may not be the cards fault. Other than that, great card when you're on a budget. Oh yea don't read the first review...

Pros: You don't need to supply it with Power... it's a kids card, so it's about as teeny as they come. If you like small and expensive, this is the card for you. 3D business graphics rating dropped 2 points in Vista from my Geforce 8800 GS Superclocked! Whoohoo! 64 whole stream processors! YAY!

Cons: This card does not benefit the typical video editor/aspiring video editor who is not running 3-d or animation plug-ins. You don't need it. This card is apparently based on the Geforce 9600. They say we pay for the drivers for business solutions. My solution is to get a Geforce 250 to replace this

Other Thoughts: Get a fast card with about 512MB of memory. Gamers might need 1GB or more, but not anyone using Adobe CS3 or CS4 and doing typical video editing, transitions, etc. Besides, you're better off getting a great processor Intel Core 2 Quad 3.0GHZ, overclock the thing to 3.6GHZ, 8 GB or more of memory, and a couple of Raptor hard drives, a Geforce 250 Superclocked and you're set.

Pros: Newegg & Nvidia, of course.

Installed without issue into Dell Precision 390 with 3 GB and XP Pro.

Cons: Screws on DVI port unscrewed when I removed the DVI. No biggie.

Other Thoughts: It works! Hopefully the processor (e6300) will be the bottleneck now. I will update later after using for a couple of days. It will be used with AutoCAD & MicroStation and also Google SketchUp, which has been my main reason for wanting to upgrade. The models we have been working with lately have gotten pretty large, and it is getting slow.
