HD 5870 CF verus HD 7970

How much of an increase will I see going from a HD5870-CF to a single HD7970 and is it worth it?
Would like to get the XFX Double D FX-797A-TDBC Radeon HD 7970 Black Edition from Newegg.

  1. dont you get superb frames with 2x 5870.... i dont think you'd get much boost from a 7970 if any boost at all
  2. Well coming from a single 5870, you have a nice setup for FPS. However what you cant do is turn on all the eye candy. Thats why I opted for a 7970 over buying another 5870. Im not disappointed at all. Sure makes things look pretty :)

    If you make that move it wont be for performance, it would be for eliminating any crossfire issues you may have.

    Check the different resolutions and the overall summary % differences in the review below. The 5970 is 6% slower than the 7970 and two 5870's in crossfire is slightly faster than the 5970 if I recall correctly (its usually the case due to the clocks not needing to be scaled back). So your performance will be very similar other than in games that do not work well in crossfire.

    Let me put it this way, two 5870s in crossfire is faster than my 580 in most situations, and I wouldnt go to a 7970 from my 580. So like I said, it all depends on how happy you are with the functionality of crossfire. Hope this helps.

  4. Yeah their great on all my games and SQL Programs. I just got a few bucks to burn and if I don't put it in my pc, I'll just blow it on something else, like the wife and I already gave her some cash. :)

    In that case then you should definitely put it towards your PC ;) another thing to consider, getting a 7970 now, and then adding another down the road for crossfire. Or if you can spring it, it will be a bit more but two 7950s in crossfire would be solid.

  7. Thanks for the link. I'll blow the cash on my wife, since I don't have room for a second monitor. :D
