Upgrading Graphic Card

I am thinking of buying Sapphire HD7770 Vapor-X card to replace my old Nvidia 9500GT card. I wonder if my system will bottleneck the graphic card? If it does,how much performance decrease will i see?

Mobo : As rock N68c s ucc
PSU : 500W
Cpu : AMD Phenom II X2 555BE 3.6Ghz

Sorry for my bad english

  1. Best answer
    There no way to tell, will it bottleneck or not. But it will surely not. That processor will easily handle it.
  2. I think your PSU is more worrying, we need a bit more info on it
  3. 500w is enough power, but your PSU should be a good quality one like Corsair or Seasonic.
  4. I currently using 30$ psu. From u guys were saying,i think my psu cant handle it. Can u guys suggest psu around 100$?
  5. Thanks for quick reply. Really appreciate all help :)

  7. Well

    Xfx Core Pro 550W

    Would suffice you

    Its made by seasonic and way better than Cx 600.

    Don't buy a power supply unless you have problems-500 watts can handle a 7970 so she easily handle yours

    That depends. Since the PSU is $30, it might not be a continuous 500W, meaning you can't actually use 500W, maybe only 300- 400W
  9. Well tell us the PSU model.
  10. even if your psu is 30$, it can handle a 7770 easily.
    don't bother to get a new psu, unless u have prob. with it.
  11. 7770 need ~85W so to be sure tell use the brand/model.
