If you do 3D work, if you need 1.5GB of dedicated GPU RAM, if you're a professional at anything graphically intensive.
Don't knock it if you can't afford it. Don't knock others for needing something you find superfluous.
I prefer Nvidia because they kick the crap out of ATI every year. And ATI always lies about how fast their new cards are going to be.
ATI says their latest card is going to be the fastest every year right. Then they come out and they are not as fast as the current Nvidia card; which by the way is about to be updated within a month or so from the ATI release. So essentially ATI's cards are **** every year and not worth the price of a new card because technically they are about as good as last years card compared to nvidia.
i don't understand the question - "which company do you prefer"?
it doesn't matter does it? You buy the best card you can afford at the time. Whether it is made by ATI or nVidia is irrelevant? If the current best card is made by ATI you buy an ATI card?
If you mean which is the better card the MP offers at the moment, again it shouldn't come down to which 'brand' you prefer - if you need V. HIGH end 3D graphics then you get the Quadro.
Personally i've been using Maya, Final Cut, Motion and Livetype in the last few days and i've got the ATI 2600 and i haven't noticed anything that has made me think, i wish i had the nVidia or the Quadro.
Don't all be too quick to jump on the 8800 card - the 2600 is a good card. Look at what you need to do (I don't want to play games, and have found in the past to have some graphics anomalies with an nvidia card)
As long as the card supports all the latest OpenGL standards and runs cool and quick thats all i care about.
Remember a lot of the tasks you might associate with the graphics card (rendering for example) get offloaded to the CPU (though some software is starting to utilize the GPU) so with 4/8 cores the Power of the PC is more important than the power of the Graphics card.
I love how even when apple limits your choices to three cards, we can still have a discussion about them.
The stock ATI should be fine for most things. If you plan on doing something graphically intensive (gaming in windows, working with prof. video apps), then maybe the nvidia 8800 is for you.
I see no reason to get the quadro for normal computer use--it is almost exclusively for specific graphics applications--I'm assuming you'd know if you use these things, if you don't, then you don't.
All that said, if you think you do more than "light" gaming, I'd get the 8800.
I don't believe so. My 7300GT can handle 8-bit & floating point (32-bit). It used to be that only 1900XT supported 10/12/16-bit, so I'd guess that it's driver issue.isn't that more of a CPU issue?
although i do know color is beginning to shift more and more of the rendering off to the GPU
My first card was a Nvidia Ti 200 which ran Maya 4 really well while I was a university, then I was convinced by the ATI 9500 Pro.
Bad move, subsequently I had a string of ATI cards including 3 versions of the 9800 Pro XT. I found the drivers to be the main problem as they were inconsistant. ATI would update them what seemed like every 2 weeks and you weren't sure how different programs would be effected. Some would work well with new drivers and others wouldn't. They just weren't that stable.
Consequently I have swapped back to Nvidia (6800 XT) although not for long, the days of the PC are numbered. It's a shiny Mac Pro for me with the 8800 powering the beast!
thats quite a sweeping statement! "PCs days are numbered"
PC days are numbered for me is more what I meant. I suppose the biggest problem I have faced over my PC lifespan has been the inconsistencies with quality of components. The market is flooded with too many companys offering the same products.
This is the case for the GPU market as well. At the end of the day all that any user can ask for whether that being on a Mac platform or windows based platform is a reliable base to be productive from. For most purposes Win 2000 Pro was fantastic, solid as a rock. XP has got better over time but not without a huge number of updates, and well vista is just plain annoying. Aside from security updates in windows I have never felt any major incentives to upgrade my OS. But I digress.
thats quite a sweeping statement! "PCs days are numbered"
It all comes down to the OS; to be blunt, Vista is a failure - mostly due to bad marketing rather than bad engineering, as such i hear MS are accelerating development on Windows 7. If that has the features they promise, it could knock Mac OS X sideways. Some of those features would be the sort of thing apple would offer in Mac OS 11 rather than 10.6 (look them up!)
I'm a convert (2003) and am happy to stay with Apple OS through thick and thin (i've forgotten how to use much of XP!!), but if Windows 7 is a good OS, then the PC world will be very happy and have no reason to go Mac.
Anyway, back to Graphics Cards! I've seen anomalies in maya with NVidia cards (very small and rare mind), i know someone who swears by FireGL cards due to their superior OpenGL 2.0 implementation but Apple doesn't offer FireGL - they must have a deal with nVidia to only offer quadro cards
