Is my PSU holding me back

Hello,

I recently upgraded most of my system, this is what I'm currently running:

Gigabyte GA-880GA-UD3H Mobo
Radeon HD 6870
AMD Phenom II 970
Hitachi 728080PLA HD
8GM DDR3 1300 Ram

I currently am trying to play the latest games (Star Wars) and am getting very choppy playing and low FPS on high settings. I know this configuration can pull higher settings.

My current PSU is an Antec 430 watt, but it only has 16A on the +12V rail (there are three of them though). Could this be holding my whole system back?

No, your too low of a power supply can only cause power failure not low FPS. I recommend getting at least 650W.

Any suggestion on why I'm getting low FPS. Friend of mine has a similair system with a Radeon 6850 and same processor and gets better FPS in the same game.

Your graphics card and mobo might not be corresponding well. In addition to that, the 6850 should have a bit more power to keep it running comfortably. I would try playing some other games though, and see what results you get.

I have a 6850... It is a good card but by no means is it a screaming gamer.

Did you load the 12.1 drivers and catylst from AMD? There are OC tools in it. I have bumped my GPU to it's max but the RAM will not go above 1100MHz.

...and get a PSU over 500W Bronze 80+

I have the auto driver install and it says I have the latest drivers at 8.920. I checked the specs and the 6870 is just a bit better than the 6850, I don't understand why my setup is running slower than a setup with the same ram/cpu and a 6850 >:(

your psu is fine.

the antec is more than enough for a 6870.

try uninstalling the drivers and reinstalling them.

You don't need a 650watt PSU to power a 6870... Yours should be more than enough so don't listen to the people telling you to upgrade your PSU unless you're planning on overclocking CPU or adding more HDs/CD drives. Do other games run similarly? Maybe you're just expecting to much out of your system. Try reinstalling drivers like the poster above said.

I overclocked the CPU by a few hunder MHz, nothing insane. Other games run amazing, I guess the issue I'm having is that my system will run the game on Low settings, and still chops a little, while another system with a lesser vid card runs the same game at maximum settings flawlessly.

Well I believe that Star Wars game just came out recently so the drivers probably aren't as optimized as they could be for that game. Try some older ones and see what happens.

Maybe it's because this is my first AMD card... but I can't find previous driver versions for the life of me on AMD's site... anyone know where I can find?
