Do ATI cards work better with AMD processors?

I made the switch from X2 6000 and a 8800 GTS 640mb card to a 1GB 4870 and a quad X4 955 and never looked back, big improvement. Everyone I talk to says yes they are optimized for each other, work together better. Only thing you will miss is PhysX in games, not a big deal to me. Im waiting on ATi's announcement this Thursday on their DX11 cards, the 5870 in particular and see the differences.

ok. thanks for answering!

AMD would like you to think so.... but not so much.

older drivers were "shady" when it came to crossfire scaling on the intel processors, but w/ 9.8 its good as gone

Bollocks.

look at all those results in depth and look at the cat drivers and tell me thats bollocks psycho.

i looked into it cuz i switched from 955 to 920 and saw a few reviews with similar resulst, and somewhere on here people were talking about it too

Yeah, but there results are clearly wrong as I get perfect scaling in games like crysis and have done for quite a few driver revisions.

That is one site using very weird labeling of graphs and again, their results don't match my own as far as scaling goes in crysis.

Nope, if you didn't read my post, I said I get perfect scaling in crysis, i.e without crossfire 15 with 30.

You can't improve on that, how can there be issues with intel cpu's and scaling if I get double the fps?

Seriously, the idea of AMD doing that makes no sense. If it was the case, why haven't every major site been grilling amd about it and it not making headline news and spawning hundreds of forum threads?

Also, in that review you posted, they had systems with different processors running using only one resolution without any attempt to use any analysis at all.

Oh, please post these sites and some evidence, I find it difficult to imagine how you can test such a thing.

I mean how can you isolate the driver in a test setup like that?

I suppose you would have to use an nvidia setup to remove the ati element to first try and guage the cpu's abilities to make sure that they match up as close as possible, a stock speed cpu like in that test you linked to is no use and it would have to be calibrated per game as well.

Then you would have to swap over to a fresh install and test it again using the ati cards and even then, could you be sure it was the case?

I know alot of idiots abound the internet who have purported this sort of thing for years and twist things to suit their causes, so you have to be careful.
