First 4870X2 review (including crossfire results)

[TheMolecularMan]

BTW, the 4870X2 doesn't seem to be taking advantage of PCI-E 2.0 bandwidth.

I know these graphs are not the exact same resolutions, and I'm not sure about the AA or AF, but it looks pretty close. On a P35 board (PCI-E 1.1), the 9800GX2 only pulls 3 to 4 frames less on FSX than the 4870X2 on an X38 board (PCI-E 2.0).

If your in the market for a 4870X2, don't convince yourself that you have to upgrade your motherboard just to get PCI-E 2.0... P35 boards will do just fine.

Well, Newegg is now listing the 4870x2 for sale now. Launch price approx $559 for the Sapphire one, the cheapest one available, for now.

But check out how the 4870 single GPU is beating the X2. Obviously the game isn't benefiting from crossfire (or even using it for that matter), so its hardly definitive that its not using the bandwidth in general.

Now the question of the day is.

Do I just get another 4870 for CF, or do a 4870x2 + 4870 x3 CF setup. I think my wallet is about to hate me

trifire did not do much in the few places that it was reviewed, and the extra memory doesn't seem to add anything unless your playing 2560 by 1600, in short the second 4870 would be great, anything past that seems to be rapidly diminishing returns.

Thanks for posting that, tomshardware does not seem to want to load that page and I wanted to see it just for the FSX part...which is the only game I am actually concerned about. FSX is not friendly towards SLI or crossfire and has always been more about CPU then GPU, I was hoping they did something different with the 4870x2 and it would actually run FSX better, but looks like my 8800gtx is still close to as good a vid card as FSX will take advantage of. Anyone know of any other benchs with the 4870x2 and FSX?

I'm the only NKD allowed, shoo!!!~~

Also: nothing is CPU bound at 1920x1200 or higher with AA on.

yea when you put dual hd 4870 x2 it is bro, and specially running at 3ghz. hd 4870 x2 in crossfire is overkill for 1920x1200 even with AA on.
