Has anybody heard of Graphene?

I was reading in one of my computer mags, it says that it is the strongest material ever. It (the mag) says that cpu's could reach 500 to 1,000GHz! It was decovered in 2004. It is made out of carbon atoms arranged in a hexagonal lattice. As a result of this reduced resistance, the substance generates comparatively little heat.
Maximumpc.com or june 2009 issue.
My question is: If this material is for real, then is this the end of the fastest cpu? How much faster do we need? Can this material be used in graphic cards and how much would it help? You thoughts would be great! thanks

Its still quite a ways before it becomes a reality, i heard somewhere 5 to 10 years. Still in the research stage, georgia tech and NIST were doing some of it;

I thought Transparent Aluminum was going to catch on big myself but with the costs to produce it, no one can afford to use it.

Aren't they essentially side steeping Moore's Law now by just adding more cores? Bring on faster CPUs and I wish that myth of AMD's reverse Hyper Threading was a reality. It would be nice to throw 16Ghz of processing power at an application rather than it relying on cores and application multi-threading.

Did we already get the formula for that?

Eventually, with a conventional glass surface, degradation takes place and results in a loss of transparency," Mr. Hoffman said. "Things such as sand have little or no impact on ALONtm, and it probably has a life expectancy many times that of glass."
The scratch-resistant quality will greatly increase the transparency of the armor, giving military members more visual awareness on the battlefield.
"It all comes down to survivability and being able to see what's out there and to make decisions while having the added protection," Mr. Hoffman said.
The Army is looking to use the new armor as windows in ground vehicles, like the Humvee, Lieutenant La Monica said. The Air Force is exploring its use for "in-flight protective transparencies for low, slow-flying aircraft. These include the C-130 Hercules, C-17 Globemaster III, A-10 Thunderbolt II and helicopters.
While some see the possibilities of this material as limitless, manufacturability, size and cost are issues the lab is dealing with before the armor can transition to the field, the lieutenant said.
"Traditional transparent armor costs a little over $3 per square inch. The ALONtm Transparent Armor cost is $10 to $15 per square inch," Lieutenant La Monica said. "The difficulties arise with heating and polishing processes, which lead to higher costs. But we are looking at more cost effective alternatives."
Lieutenant La Monica said experimenting with the polishing process has proven beneficial.
"We found that by polishing it a certain way, we increased the strength of the material by two-fold," he said.
Currently, size is also limited because equipment needed to heat larger pieces is expensive. To help lower costs, the lieutenant said researchers are looking at design variations that use smaller pieces of the armor tiled together to form larger windows.

I think the Graphene was actually used as a multiplier, so heat is still a major limiting factor
