Radeon HD 6870 Crossfire Game Requirement Analysis

Radeon HD 6870 Crossfire is a solution of two Radeon HD 6870 put together using AMD'S Crossfire technology.
Check the page of Radeon HD 6870 to know more about its chip.
Crossfire relies a lot on proper driver support and may suffer from micro-stuttering in lower frame rates (below 30). Benchmarks indicate the performance is overall, is up to 67% better than a single Radeon HD 6870 performing by itself but it might be worse (depending on whether or not the 3D game supports crossfire or in the graphics driver) than a single Radeon HD 6870. Expect this combination to draw up to 302 Watt though the average power consumption should be slightly lower.
Even the most demanding games will run at the highest settings.

a single 6870 @ 1ghz is only 15% worse than cfx :( I'm disappointed with the scaling

Have this card "Powercolor 6870x2" its really good, playing Crysis 3 on high settings! =) havn't had so much problems..only with one game really and its Assassins creed 3..where i got some odd frame drops…but im hoping for some crossfire driver support on that game…other then that no micro shutters or anything! if only AMD Catalyst was better ;) hehe

For those who wish not to waste PCI Express 3.0 Cards on their aging PCI Express 2.0 boards but still strive for the diamond standard!

What do you mean waste? Pci-e is backwards compatible and suffers no performance loss.

Backwards compatible, yes. No loss of performance? Certainly Not! As memory bus width gets larger, you need a wider communications bus for that memory! It is conceived that memory bandwidth has outpaced PCI Express 2.0, so PCI Express 3.0 was developed.

No. Imagine if you will a highway. Say pci-e 2.0 is a highway with 400mph limit, and pci-e 3.0 is 500mph limit. A car that goes that fast doesn't exist (car=gpu in this case)… So yes, NO preformance loss

Grrr…… You do prove a valid point… As a man of respectful nature, I submit to your correction. However, one question I have to postulate; if Expansion modules for PCI Express 2.0 have not reached the barrier as you propose, then why superfluously bring on the next generation if it is not needed?
