gheeD Posted June 20, 2010 Share Posted June 20, 2010 For dual GPU setup you need second HD5850, nothing else will do. OR GTX275, depending if your motherboard supports crossfire or SLI. BUT if i remember right, the other one can be used as physics card (PhysX, no use in fsx tho) or if you want many screens, you can put 2 screens to other one of them, but only get for example fsx, on one screen. IMO i would sell GTX275 and buy another HD5850 if you want crossfire. Link to comment Share on other sites More sharing options...
Phil Manhart Posted June 20, 2010 Share Posted June 20, 2010 gheeD is exactly right. While Windows 7 allows for two video cards using two different sets of drivers, you are not allowed to use them at the same time unless you are using the ATi card as the Primary Graphics Adapter and the NVIDIA card to run PhysX, which is a motion-simulating software that some software manufacturers have added into their games. You can set this from the NVIDIA Control Panel that is found within the Windows Control Panel or from the context menu after Right-Clicking the Desktop.

(specs at bottom) What you can do is wait for motherboards to start using Lucid chips. ->Google Lucid. That is supposed to allow combinations of any cards to be used as all the combining functions are done in software. It hit the scene last year to big fanfare and MSI was going to build a board with a Lucid chip and it was big news on hardwre forums. I looked long and hard as I have an 8800GTX gathering dust since I switched to ATI. Unfortunately MSI cancelled that board and Lucid kind of disappeared, but the rumours are starting to appear again. Unfortunately I don't think it is going to be as good as we originally thought but it's certainly worth keeping an eye on. So really at the moment the answer is no but that might change in the coming months. Hope that helps. Link to comment Share on other sites More sharing options...
Maurice_King Posted June 28, 2010 Share Posted June 28, 2010 NO I disagree you can run different graphics cards on the same system as long as you have 2 PCIe X 16 Slots for instance. I have 3 cards in this PC all different. Link to comment Share on other sites More sharing options...
John Dow Posted June 28, 2010 Share Posted June 28, 2010 All academic really for FSX as reported attempts to use more than one card or GPU actually slow the sim down. Link to comment Share on other sites More sharing options...

Maurice_King Posted June 28, 2010 Share Posted June 28, 2010 ONLY if you HAVE to run SLI etc must you run identical cards and slow down , not notices any John, I shall have to look at that. Link to comment Share on other sites More sharing options...
marshkop Posted June 29, 2010 Author Share Posted June 29, 2010 Ok this is what I've heard, you can run two different cards on one system but not in SLI or Crossfire. I know that an Sli system is no good for fsx. Crossfire is no good for fsx. A dual chip card;5970 - gtx295 is no good for fsx. So if you have two different cards not connected how would it affect fsx? Link to comment Share on other sites More sharing options...
John Dow Posted June 29, 2010 Share Posted June 29, 2010 Well I guess there's only one way to find out since I doubt anyone has ever tried it with FSX... you can go where no man has gone before... Link to comment Share on other sites More sharing options...
