I definitely do not think that is the FPS in the GPU Test section. It's probably just a number that indicates the cards score.

The 2900 has come miles from it's launch. Took a few months to get there, but it did. I'd pit mine against a G80 GTS any day.

And you'd still lose.

Nope. With the stock coolers, perhaps, but on water or anything better the 2900XT is the clear winner.

have you looked at any of the 3dmark forums? G80s are long behind 2900's and 3870's. My 3870 OCed will out perform an ultra.

lol. Only if the GTS was clocked, and mine wasn't.

But it doesn't matter, my 8800GT spanks them both.

There is nowhere (that I can see) in the screenshots that shows there is Crossfire enabled.
There is only a picture at the very end that shows the cards in a Crossfire config.
All the CCC shots and GPU-z say no Crossfire.

What gives? :confused:

nvm, I plugged the link into Google Translate and (as stated earlier in the thread) the drivers offered no increase with the addition of a second card.

i agree with you, man - except for the "very high" setting, my single 1950 PRO on this P4 setup pulls those same numbers at those same resolution in "high" with no AA/AF. My 1950s xFired return better scores than that.

Somethings odd about that review, IMO. We don't even have official drivers for the 3870x2, and no one was even sure if the card would support 2 card Crossfire, and all of a sudden a review pops up . . . :wtf:

Yeah hahaha... totally true. This is what happens when reviewers get too excited... >>> OMFG!!! Its SLOW in CF (b/c it does not support it yet...)

Yes... Yes it will... it will also annihilate an Ultra in any game that supports advanced features like VLIW and tesselation... unfortunately for the HD line, no games really do...

as for the X2... it is OK... but the problem with it is ... in a best-case scenario, it absolutely mashes an Ultra or two. In the worst case, however, its slightly slower than an 8800GT. Ultimately, in a game like Crysis (which is coded like dogs&*t) any of the 8800 series will come on top, because they always perform 112 or 128 or 96 shader operations per clock (@ 1500MHz), where as a HD 3870 can do 64 - 320 per clock(@ core), buuuuut mostly around 64 since VliW is not supported by dogsh*&y games.

i hear 4 gpu's only = x8 versus 2@x16

depends on the board, an x38/x48 will run dual 16x

niko084 · Jan 27, 2008

Either these drivers are WICKED horrible, or these guys CAN'T setup a computer....

My single HD3850 @ 1280x1024 in Crysis GPU bench does 28 fps 1280x1024 very high, no AA/AF

These reults are whitout crossfire. Only ONE 3870X2 working. System detects two cards but crossfire is not working with the drivers they use.

adrianx · Jan 29, 2008

the driver have problems?

the 3870x2 say... that the card will work on pci-x x16, and the chip from the card will make crossfire for that two gpu from the pcb. Also the chip dont need a crossfire mainboard in order to activate the crossfire mode.

soo the chip is ...between the pci-x slot and the two 3870

I belive that the next step will be... a dual gpu on die (like a X2 cpu or core duo)
