Which HD5850 for O/C

[Hi_Clocks]

Hey guys, Im going to be building a new watercooled rig and need advise on which HD5850 to get that can overclock well? I have heard some say MSI cards are the best and ASUS but I am unsure of which one to get?

Budget is less then $330 shipped.

Also, I am looking at cooling it with the EK HD5850 full coverage waterblock

So I want to be sure this block will work with whichever card I get, as Im new to watercooling.
Thanks for your time.

reference cards are hard to come by these days, don't know which brand is good overclocker but they should be close as they all give you the ability to change voltage.

The reference cards look like this ones below:

You can read through this review http://www.techpowerup.com/reviews/A..._TOP_DirectCu/ and you can see at lest the Asus card dose what it say it will do . It got a nice power set-up on the card and changes volts http://www.newegg.com/Product/Produc...82E16814121375 .

Would this Sapphire HD5850 be a reference card and also offer over voltage?

It seems as though that is one of the cheaper ones but O/Cs well from the reviews I read.

Reference 5850 only have 4phz power set-up 2 6 + 6 pin plugs for the video cards . The Asus video card that i posted in the link is the only 5850 that has 7phz power set-up that why you need a 8 + 6 pin power plugs to power the video cards. A person has already posted a thread in here where he was having over heating trouble with the power area on the reference video card when he was trying to over volt the card something to think about .
edit there one sapphire 5850 that take a 8+6 power plug set-up
http://www.newegg.com/Product/Produc...82E16814102890 and it cost almost $400 dollars .I don't know what it power set-up is like i have not see it with it cooler off . Sapphire make so many 5850 hope you get the right one if you order that card .

yeah that is the 2gb version also the toxic 2gb also has the 8 and 6 pin, thing is those are not reference and don't allow for voltage control.
