5750 CF or 5850?

The benchmarks here claim the 5750 CF is faster than a single 5850. But getting two 5750's only cost $260, while a single 5850 costs $309.

Am I missing something? I don't know much about crossfire, is there some big downside?

HD5850 is slightly worse than an HD4850x2/HD5750x2. However, an HD5850 OC will match or beat it. Also remember that you can CF the HD5850 with another one, thus adding much more power.

that's okay if you want to use CF setup of 2x HD5750...
but i think you will better by a single powerful GPU, in this case HD5850. It good for a long term, also you can add another one later. Single card= less heat, less noise, less trouble... :)

5850...
CF or SLI is never as good as single card

Usually the pattern to follow is to get one good card, then get another later when you need it.

Unless you get a good deal on two cards, wouldent buying old tech and filling your slots up make future upgrades more difficult?

I imagine theres quite abit of diminishing returns on 3x - 4x crossfire configs.. But i've never done it befor so im not sure.

Thanks for clarifying everyone, I'm going to get the 5850 then.

I read reference is the way to go for overclocking, because it allows voltage control.

http://www.newegg.com/Product/Product.aspx?Item=N82E16814150491&Tpk=5850%20xfx

I don't think this is reference, but I do want xfx for the warranty. I suppose OCing would void that anyway so it doesn't matter. I don't really understand why xfx has so many different versions of the 5850, and can't find any reviews on this particular model. Could this one be cheaper for them to make?

My concern is if it will cool as well as the full shroud version. I was thinking that the open heatsink design might allow for more case fan breeze to get in and better heat dissipation from within, but it's so much smaller than the other full shroud models I've seen I really don't know.

Then explain to me why people love to run a pair of 5770's over a single 5870?



why?
well some games support CF or SLI but some just don't and i prefer single card than CF or SLI..

what speed? stock?

Well, if your motherboard allowed you to unlock the 4th core of your Phenom II X3 and get your speed about 3 GHz, you will be fine with HD5850... :)
