Probably MacVidCards would be better suited to explaining this but as I understand it the 5xx series cards were matching or besting their Quadro counterparts in CUDA related tasks while being hundreds of $ cheaper. I would imagine the profit margins are larger for the Quadro cards, so Nvidia was wise to not further cannibalize their professional market by somewhat crippling the 6xx cards.So I've read that the 570 is better for CS6. And the 670 is better for games. I just don't understand why? Can someone please explain why the 570 beats the 6xx series cards for Cuda processing?
What's confusing is when you compare the specs fo the 570 to the 670. The 670 seems to outclass the 570 by a long shot yet it actually fairs better in real world GPU tests.Nvidia apparently "dumbed down" the new 6xx series capabilities focusing instead on game related features. They are not totally slow but slower than the previous gen. Since I do very little GPGPU on my system and need a gaming card I will get the 6xx series. While users needing CUDA at a fair price should get the 5xx series or get raped by the Quadro cost. I assume Nvidia did this to differentiate their lineup. You shouldn't let the higher/ lower number thing bother you. GTX570 is most likely what you want. A GTX580 requires too much power trade off IMO.
Perhaps you should just read some of the detailed reviews of the Kepler architecture, for example:What's confusing is when you compare the specs fo the 570 to the 670. The 670 seems to outclass the 570 by a long shot yet it actually fairs better in real world GPU tests.
I'm just wanting to know why exactly.
I decided to go with the EVGA 570 2.5gig version on my Mac 3,1. Thanks for your help. I installed it last night and everything's running smooth. Since I didn't have a boot screen I wanted to try running it with an old ATI Radeon 2600 XT to see what would happen. Well so far so good. The ATI is running both displays I'm getting boot screen and I'm still getting CUDA acceleration from the 570 in CS6. I really didn't think they would work together. Can you think of any reason why I shouldn't run these cards in this configuration? Is there a downside?Perhaps you should just read some of the detailed reviews of the Kepler architecture, for example:
