In this thread there is a chart near the bottom of the page. On the top of Resident evils FPS numbers sits a GPU called the 5770 CF, it ranks higher in FPS than a 5850 and in some cases over a GTX285 as well.... how is this possible and what card is this?

Its 2 5770s in crossfire

Man, I really cant believe I didnt see that.... In all honesty, that chart shown in the link is useless if you are going to compare crossfire with a single card.........

Not really, many people have CF available as an option and sometimes its cheaper to CF two lower end card and will actually yield better performance than a more expensive card, its good to know all your possible options and its always nice to see how well or poorly CF scales in each main game tested.

I don't understand how one can post 417 times and not know what CF stands for.
You do know what SLi is I hope.
Most modern mobo's have multiple full-size PCI-E lanes, P55/P45/X38/X48/X58/790G/790GX/790FX and many more. For enthusiasts who can spend enough to get a GTX 280 or 5850 they almost certainly have a mobo that supports CF.

However the 5770/5750's will give you less return in the future, if you get a 5850 right now vs 2 5770's you might get more performance with the 5770's but when upgrading either you get a 3rd or 4th 5770 & face little scaling or you cannot get more 5770's at all because you are running 8x & 8x. If you got the 5850 though, you can plug another in & get great scaling.

I like youre attitude and quote hunter.. On my part, I cant believe that i didnt think of Crossfire, haha. The charts were confusing however as all of a sudden there was a CF compared to single card configs.... thus it led me to subconciously believe that CF was a 5770 variant or acronym....

well with the card naming schemes these days your confusion is understandable, especially with most dual cards these days getting special names rather than an x2 on the end.
