Which 6800gs should I get and why? What is the difference between the two?

Also, I have a pretty old psu and am not sure if a pci-e power cable or something is needed.

It appears that the 391 has 1100 mem clock rate while the 386 has 1000 mem clock rate. That seems to be the most obvious difference

Yea I know that but I could just overclock it manually instead of paying a few extra bucks for a pre-overlocked card. Is there any significant difference between the cards that I should consider?

nothing except the core/memory clocks which can be OC'd so i'd go with the cheaper one.

Or get the more expensive one and OC that, even better .

yah the one that is preoverclocked comes with a better stock heatsink usually

edit
get the ceaper one

look under the black part of the heatsink its copper
both of them have the same heatsink so now there is no real reason to spend more money
the only reason i would get the more expensive one is the heatsink looks better

 

[pc_boy]

the cheaper one has $20 rebate, so i would get that one
