Which of these HD 5850 cards should I get? (XFX vs Sapphire)

I'd probably go with the sapphire one, but none of those cards will support voltage tweaking for the best overclockability.

I like the Sapphire 100282-3SR!

Ah, really? Someone told me the XFX HD-585A-ZNBC was the only reference card. So, can this card be OC'ed or not?

not as much but i have this card so ignore my opinion!

XFX HD-585A-ZNBC is the better card

Just a tip: stay away from non-reference cards. You will loose the option of voltage control if you don't.

Ah, I see.

If out of the three cards, I wanted to leave everything at stock speeds and do not plan on OCing at all, which card would be the best? Meaning if I just wanted the lowest temperatures & best performance at stock speeds... would the XFX reference still be cooler and better? Would it not be until I do some heavy OC'ing then the XFX reference card be better? My understanding is that reference cards push air out of the case while non-reference pushes half out and half in (perhaps to make the GFX itself stay cooler?), but I would also want my CPU to stay cool as well.
