Hi, new to the forums, and have used the search function to the best of my ability to find the answers to this, but can't quite get what I want. Thanks in advance for the help!
I currently have a 750W modular powersupply
p8p67 pro Rev 3.0 motherboard. First pcie slot is x16, next would be x8
Running XFX radeon 6870 card (XFX HD-687A-ZNFC)
I am getting idle temp of 48-51c after upping the fan speed with manual, and topping out at 75c under load.
I am interested in Crossfiring this with the 2 fan model with the same base clock speeds
XFX Radeon 6870 XFX HD-687A-ZDFC.
Will this setup work since they are two different cards?
Is my power supply strong enough?
I have never Crossfired before, so will one card be a "main card"? Should I use the dual fan model as my "main card" so I can have lower idleing temps?
Will this reduce stress on each card and ultimately give me lower temps unless both are under full load? Or will both cards just be under full load and produce better frames and image? If there is any additional information I am not thinking of in regards to this, please let me know. I am a bit of a tech-beginner, and these are the only immediate questions I could think of.
