Nice work mascaras :clap:

Soooo....
HD4850X2 =~ 9800GX2 ||
9800GX2=2x 8800GT (G92) || ==> HD4850=8800GT (G92)

Nice... kinda late, but still nice :)

Mascaras is that possible to place the results on a table?

I think your great efforts are really well appreciated, however misunderstood by some forum members by the fact is not clearly organized. Keep the good work up :)

Metroid.

Thanks for the comprehensive tests and for the numerous in game screens. :bounce: We wait for more:up:

According to GRID help file (or readme file), the game is not optimized for any dual card config. I think I read this.

However when I play it with my 8800GT SLI, both cards are pushing, the temps on both cards are identical.

I suppose the same thing happens with two cards in CF.

The official driver for RV770 looks like to be 8.7, cause in 8.6 there is nothing said about these cards ;).

Nice scores :up:
Can you compare a 4850CF (~440$?) vs. 8800GTS 512 SLi (~340-400$)?

Very nice review, mascaras!

Could you, please, tell us if there is any micro stuttering when running in Crossfire mode? I know you already told us earlier that in Crysis there are some lock-ups, but what i refer to is this.

Cheers!

@mascaras
Could you test Age of Conan with HD4850 Crossfire please?

thanks :)

you´re right , i started testing single card today , and guess what???

1920x1200 AA x2 ultra settings = almost same Fps as CF (70/95) :shocked:

so i guess the game dont scale well @ Multi GPU (same hapens with GX2 and SLi) , however the good new is that single hd4850 can run the game @ 1920x and AA with very good FPS :)


im uploading the SS



edit: added Race Grid @ single card

added COD4 singleplayer @ single card


added 3dmark vantage Performance test @ Single card




:up:

Mascaras, any info about the hotfix?

Thanks!

the first part of review was hd4850 Crossfire with CAT 8.5 , the only single card test i done @ 1st part of review was the crysis but i also tested today with Cat 8.6 and same thing (also in CF no gains)


i only started 2nd part review today @ testing single card in Games but already with cat 8.6 ( i didnt test singl card in games with cat 8.5 before, so i cant compare :( )
