Radeon HD 4770

Ok, it's a new card lacking driver support right now.

I bought two of them and scored 14500 singular and 18500 xfire in 3dmark06 on my friends system. That was with bad drivers.

Catalyst 9.5 will be released either tomorrow or very soon and that should give us an idea of where the card truly sits in performance. With the dodgy drivers I've found it to be at least as good as a single 4870 in most games. With proper drivers two 4770's in crossfire will be faster than any single gpu available right now, including the 285gtx.

Crossfire isnt difficult to set up, just get 2 cables (the 4770 doesn't come with any), put both cards into your pcie slots, switch on crossfire in the catalyst control centre and that is pretty much that.

What card do you have right now?

Yep you'll be fine

This is your motherboard right? - http://www.neoseeker.com/Articles/ [...] 950/4.html

You can actually take 3 graphics cards. I wouldn't hesitate to buy a 4770 if I were you, and add 1-2 later.

According to that review, the blue one is the normal pci-e slot, the white one is used for 2-way crossfire and the black slot is used with 3-way.

Should be one helluva system. If you do decide to get 3 4770's please let us know how it works out.

I think it's that way by design tbh.

The first card draws 16x like on any new mobo. Two at 8x8x isnt unusual although that might lead to a slight performance loss vs the extreme high end systems.

The 3rd slot being 4x makes a lot of sense really, considering the drop off in performance when using 3 cards. That third card will always be underused so it doesn't need to be running at 16x. I believe the figures for crossfire/3-way are something like 80% 2nd card/40% 3rd card so 4x should be good enough on that third slot.

It depends on whether or not you have an FX or GX mobo. FX have more lanes and for sure will work better in 3-way or higher crossfire.

I think that taking the nature of the card into consideration, it will probably run very well on that mobo even with only 4x on the 3rd slot. I have a 16x/4x 780x mobo as well as an 8x/8x 790gx so I'll try it out and see how they compare.

You need two crossfire cables.

when and if i decide to get a second 4770 will this have enough juice? http://www.coolermaster.com/produc [...] il&id=3738


any clue on when the drivers will come out for the 4770?

I have tried to d/l the files but keep being told they are invalid links... I will try later today, again. I will say that these cards are pretty quite. I have them both in the case and the only time i hear them is on start-up, they are loud then and only then. Oh and by the way only needed one crossfire bridge to hook up two of them. Was waiting for the new drivers before I did any test.
