Do ATI video cards work better with AMD CPU's than Intel CPU's?

Can you explain? Is there something that you've read that proves this?

No.

It doesn't matter which CPU you pair it with.

^ Haha . And No it doesn't really matter. I have a AMD CPU with a Nvidia card I don't see any differences. My HTPC is a Pentium 4 with a ATI HD 3650 no problems here .

Its just marketing, since AMD owns ATI now they would prefer you have both their CPUs combined with their graphics as well. Ive always had AMD cpus minus the Pent 2 400mhz I had 10 years ago. Recently had a X2 6000 cpu bundled with a Nvidia 8800 GTs 640mb card and games ran fine. Curently I went with a Phen 2 955 and a ATI 4870 1gb and everything runs great as well!

Could be we just never would know! because the intel and amd cpus vary usually in different application it's more or less apples to oranges when comparing cpus in a price range. But if you're a true fanboy liek audiophile you will believe it does no matter what proof is given to you.

It shouldn't matter, although I believe Crossfire could run better if the GPUs were paired with an AMD chipset.

I think the EU would say "Doing what? We dn't see anything"

j/k

The only time a GPU runs betetr with a CPU is only when the GPU is no longer the bottleneck, mainly in multi card setups. Thats the only time you will see much of a difference between the CPUs. But when its a single GPU they all run the same no matter what.

The short answer is no

But AMD will do this at 2011. Ever heard "BullDozer" and "Fusion"?
If not, get your lazy bones up working hard to type "Bulldozer AMD" then pick ones with wiki. Read it then click the link that says "Fusion". There's you go.

I didn't say PhenomII, I said Phenom. There is a difference. Learn to read before voting a post down. I would be willing to bet that most people running AMDs in their systems are still running either an X2, or an original phenom. PhII are to new, and haven't sold as many.
