  2. That psu is a bad one, not recommended for a 7850(doesn't mean it will not powerup the card and the system within).
    Also there's a performance increase not decrease from a 5670 for a 7850.
    See if you can buy a new psu, if not i'd just get the 7750 amd.
  3. Would be an XFX 550W be enough?
  4. Sorry for my bad english
  5. And in the first post I wanted to know if there will be CPU bottleneck in gaming.
  6. Yes, the xfx 550w is a good quality psu.
    With a 7850 and that cpu there're will be no bottleneck.
  7. Thanks
  8. Ok i didn’t buy the hd 7850. I bought an xfx radeon hd 6870 double dissipation. My question is if the XFX 550W PSU will be enough for this card or should I buy an XFX 650W.

  9. The 6870 is a pretty decent card, should do you well.

    I have the XFX 650w powering my 6870 but i suspect the 550 would do the job as its a seasonic PSU. I only went 650 for the modular cabling.
  10. But would an XFX 650W or XFX 550W fit in my case. My case is COOLERMASTER ELITE 332
  11. I don't see why it wouldn't, your case takes standard size ATX PSU's and both XFX's are ATX sized PSU's
  12. True, you'll only need the 550w for your configuration and why you chose the 6870 and not the 7850, they're at the same price and the 7850 offers much better performance and it's from the newer generation from amd.
    But it's not a bad card, it can play any game @1080p.
  13. Because I bought that card from someone for 155$ where the new HD7850 costs 230$ in my country.
  14. Even the 1GB ? :O

    But it's not bad if it's those prices, the 6870 is slightly better than a 650ti/560(non-ti) for that range.

    Yes, but as i said this card is not new. I bought it from someone.
  16. If you managed to get a good deal on it compared to a 7850 then it's worthwhile doing, as mentioned it'll play most games at 1080p.

    Compared to your old card it'll be a big improvement.
