We are buying a machine to run a Unity application in a museum.
We are considering getting the Geforce GTX 285, but then I was reading this thread
http://forum.unity3d.com/viewtopic.php?t=20640
about the gtx 295 in which people say that the whole gtx series consistently underperform compared to lesser cards.
Is this true?
And if so can you recommend a card we should buy instead?
The GTX295 is a SLI onboard card.
That means it has 2 GPUs running in tandem
Thats where the problem comes from because the shaders aren’t written for SLI configurations but for single card solutions. These shaders often assume that the same card handles now and the next frame, but in sli thats commonly not the case and as such the second gpu has to wait all the time on the first gpu to syncronize the frame, they can’t render ahead. As such they normally become slower than a single gpu would be.
If these users:
the problem is commonly resolved.
Ok. But since the GTX 285 is a single cpu card it shouldn’t have these issues I presume.
I was more worried about llavigne’s comment that all the GTX underperform compared to lesser ati cards. Is that a fact?
I basically just want to buy the card that gives the best Unity performance for the money, since the machine’s sole purpose is to run a Unity app.
I’m on a Core i7 + GTX280 + 4 disk Raid5 and no probs here.
The GTX285 is an indirect / overclocked successor of it so I doubt you will see problems other than the room cooling ^^
You’re running such a high level card that you probably won’t have to worry too much about performance. Well, unless you’re running a game that was made to push the card to its limits. But the vast majority of Unity apps can be run much less robust cards.
cool - thanks for the advice
