Workstation and Gaming Video Card in the same Computer

post #1 of 9
Thread Starter 
Hi,

I've searched a lot concerning this question, but no one seems to be able to answer it correctly...

I'm using my computer for both gaming and CAD. I use mostly CATIA, Soldiworks. I'm having a few big projects related to engineering and my computer seem to lack a bit juice on the GPU. I've recently got myself a second 5850. I thought this would help. While gaming, I see a great performance boost, no problem maxing any game. But when designing, the performance is worst than before. The program can't refresh correctly and the image is freezing, it is pretty weird. A few other people had this problem, Crossfire related.

I'd like to know if it is possible to add a third card to my rig, and configure it so that when I do CAD, the system uses the workstation card, and same thing with gaming.
Of course, this would be an ATI firePRO.

Here is my rig:
i7 920 @ 4 Ghz
6Gb ram @ 1800Mhz
2X Radeon 5850 @ 875Mhz
Gigabyte X58a-UD3R MB
Watercooled: CPU, GPUs, Chipset. Mofsets, Dualpump D5

Thank you

sell them and get 1 HD 7970 or HD 7850 Cfx?

As I said, part of the problem came from being in Crossfire. 7850 is not an option to solve this problem.

A single 7970 would not worth selling two 5850 to get pretty much the same performances in gaming. And by changing from two to one gaming card, we are still having very poor performances of gaming card when used a CAD program.

The question was:

From what I'm seeing it's not likely that you'd be able to have both in the same system. You could always dual-partition your hard drive and swap the cards out when you wanted to do work/games. But, to me, that's just not practical.

This could be a possible solution, but you said it, it isn't practical. I've send a message to ATI and I'll see what they answer.

Well, one of your problems is running ATI cards for a workstation. Nvidia plays nicer with professional programs (typically), even if you have a Fire GL card. Secondly, I'm not sure if Solidworks or CATIA takes advantage of professional series drivers, or not.

Step 1 - Figure out which programs work better with which manufacturer.

Step 2 - Figure out if a professional series card is worth the upgrade.

Step 3 - Don't try to run a gaming rig on a seriously professional workstation, unless all of your programs cater to gaming series cards.

I've heard that one quite often, but after searching a little bit, I've realized that it was completely false...

The relative performance of the cards varies greatly from test to test, making it impossible to declare any of them a clear winner – or even to declare a winner between Nvidia and AMD.

Solidworks will work with both Nvidia and ATI pro cards. All recent pro video card are certified here: http://www.solidworks.com/sw/support/videocardtesting.html
Many features are disabled with gaming cards.

As you can see with the bench, the FirePro V4800 can perform the same as a Quadro 4000, depending on the software. I think it is a pretty good choice! The price is ridiculously low for a pro card.

The goal of this post is to know if I can avoid to get two rigs when the only thing that would be different is the video card.

Hi,
Same situation here, getting a new workstation rig and want to be able to install a gaming card.
No solutions so far but if there's a way to disable one card in the OS (which I think is possible, yet to try) then you won't have to physically replace the cards, just have a dual-boot and all you need is a restart to switch between the two.
