http://www.newegg.com/Product/Product.aspx?Item=N82E16814130752

by the way, this upgrades for playing swtor, so i would like to know you guys' opinion on which card would be better.
i have an average understanding of graphic cards, but i see one having higher core clock, etc, so i have my doubts.
One more thing, the amd card requires 500w and my psu only has 430, heres the link

but ive been told that what matters is the 12v rail and mines has 12v+ 28amps which is 336, wouldnt that be enough to run
the 6850? thank you for your time.

They're both about the same, so it's a matter of preference really.

Either one:

As far as amps?

6850 = 6pin + PCIe so 75 * 2 = 150w / 12v = 12.5amps

GTX 460= 6pin + 6pin + PCIe = 75 * 3 = 225w / 12v = 18.75amps

Formula for watts~

Voltage * amps = watts
