7950 vs 6870CFX

Upgrading my PC in a couple of weeks. I'm going back and forth between getting 1 Radeon HD7950 or 2x Radeon HD6870. Which do you think would perform better. and can I even CFX with a PSU that's only 550w. I'm not planning to upgrade the PSU yet.

CM HAF X
AMD Phenom II X4 965
OCZ Fatal1ty 550w PSU
Corsair Vengeance 8GB (2x4GB)
CM V6GT Cooler

  1. Title is wrong* Its 7950 and 6870 x2
  2. Go with the single HD7950 at least there will be no micro stutter and performance not far of. 550watt would be low for the CF anyway.
  3. To be honest you can handle almost any card with 500+ watts. To all power freaks I'm not saying it is The best option but it still would work. Some guy ran 560ti's OCed 2 HDD's and like tons of RAM with a 600w. It was also OCZ. But to answer your question I think I 6870x2 is better as most people compare the 6870x2 to a 7970. But you will probably get similar performance with either.
  4. HD 7950 for sure ?
  5. Wait change that. I didn't realize you meant crossfire I thought you meant there was a 6870 double card. I would go with a 7950, it leaves more room for upgrade and uses less power.
  6. 7950 will beat 6870's x2 any day...i had both... lol currently have a 7950 overclocked past 7970 performance
  7. Personally I don't think your PSU is strong enough to crossfire HD 6870s.

    I would definitely go with the HD 7950 but I am not sure of it's power requirement.
  8. Ive heard that the 7xxx series has alot of driver issues. You guys experience anything?

    I havent, I just troubleshooted someones 7850 today pretty quickly. usually if there is something wrong with the stable driver, using another version/beta driver fixes it most of the time.
  10. Go for the 7950, can add 2nd 7950 later. Or even the 7870

    No upgrade path getting 6870.

    And a 650w PSU would be just fine.

  12. Thx everyone for their input. I actually ended up getting a VisionTek 7970 got a deal on one for $389 at MicroCenter. It's running great. Playing ffxiv on my 5770 was really laggy. But with the 7970 I have the graphics turned up and everything is going great.
