View Full Version : SLI system - one game card, one 3D work card
02-17-2006, 01:20 AM
So I'm specing out an Alienware, and the motherboard has got these specs:
PCI Express x16 Slots: 2
PCI Express x1 Slots: 2
PCI Slots: 3
Now the fundamental problem has always been that a high end gaming card is different from a high end 3D visualization card; you can't get one that does both well. Would it be easy to install one of each (say NVIDIA GeForce 7800 GTX for the gaming) and a NVIDIA QuadroFX for the 3D work? And then switch between the two in System Properties or whatever before you open Maya?
The card in this school system here is a Radeon X800 Pro, it runs Maya & games, as to how well, I have no idea...
you might be able to figure out how to switch between them easily, but that would not be SLI.
Indeed, SLI is a technology that combines the power of two or more (IDENTICAL) cards for one monitor output.
You can plug two different video cards into those two PCIe slots, but it would not be SLI. Insted, you'd probably be able to have two monitors for your computer. One (the primary) would be for running games (the Geforce), and the secondary monitor, run by the Quadro, could be where your Maya workspace resides.

has anybody documented trying this or...?

I have tried this and it seems windows or Nvidia drivers was not written for this and isn't smart enough to know what to do. (two monitors also)
Which ever card you had to to Primary Display it will use that card as to what to do. But still as that it gave werid results here and there. Even with that limitation, i got slowdown ALOT. Settled with a 7800GT... waiting for a FireGL based on a X1900 or better to come out : / as those are semi affordable and should be 99% as good as the gamer GPU for games.
I wish you luck and i hope you get it working, if you please post back.!
I run 4 displays at work, each off a different card (Mixed ati and nvidia). I've never experienced problems, however most of my monitor usage at work is alot of IT stuff. I hardly stress the 3D abilities of the cards (what little they have :)) No matter what though, Windows will favor the primary display for most things.
Its a bit of a different picture on Linux, where I can specify which display runs on what driver, etc. more easil (in my opinion:P)
I may one day have an extra graphics card. I can put it in and give it a whirl. Until then most of my experience with multiple video cards has been rather uneventful and problem free..

Awesome...let me know if anyone has success with this. I don't know much about it, but am very curious to if it's possible.

I have a single Radeon X850 in my machine. It runs both Maya 7.0 and games wonderfully. I haven't had a single problem with it yet. ^_^

"Now the fundamental problem has always been that a high end gaming card is different from a high end 3D visualization card; you can't get one that does both well."
I have to say this isn't true.
I've been running a geforce 7800 with xsi and maya and haven't had 1 issue with it. It's an amazing card for 3D.

Maybe this one isn't for this thread but...
How is Quadro 4500 with games? :)
After some time working I'll probably gonna shoot something so... anything for this? :))
I'd expect a Quadro to do quite well in games. Maybe not as good as its Gefroce cousin, due to driver optimizations, but I dont expect it will be horrible. Like the Geforce does in CG, it can probably bruteforce its way through some games even though the driver support is not as good for this type of application.
