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

There no way to tell, will it bottleneck or not. But it will surely not. That processor will easily handle it.

I think your PSU is more worrying, we need a bit more info on it

500w is enough power, but your PSU should be a good quality one like Corsair or Seasonic.

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

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.
