ASUS W90Vp Overclocking
What about the 15% overclocking option on the ASUS W90Vp? We gathered results from all 17 titles that we tested to find average performance boost from the CPU overclock. Note that for these results, we used the initial driver except for Empire: Total War. We are overclocking the CPU and memory 15% (technically 14.5%, but who's counting?), so unless something else comes into play we shouldn't see performance increases above that amount. And yet….
Riddick: Dark Athena is the one title where we actually see a performance drop. Considering the driver issues in that title, we're not entirely sure what's going on. Performance in our benchmarks is very consistent, and it simply ran slower when overclocked. (If we get a minute, we may see about rerunning the test with the updated driver.) The more surprising result is that four of the titles show greater than 15% performance increases. FRAPS testing can be more variable than other canned benchmarks, but again our results are extremely consistent for the titles in question. For more titles show little to no benefit from overclocking the CPU, indicating they are completely bottleneck by the GPU. The remaining eight titles improvement in performance between 5% and 15%, with the majority falling closer to 15% and only Mirror's Edge showing a 5% improvement.
Keep this information in mind, as it shows that the majority of the titles we test with are performance limited because of the slower clocked quad-core CPU. Then again, three of the newest titles that we test are bottlenecked by the graphics cards.

Well. . .If there was a PCI-e standard for mobile, then maybe you could choose your graphics and the laptops would have to work properly with standard drivers?
What if you used DisplayPort for the interface to the display? Then you could plug in any graphics chip and it would work with the standard drivers.
You would of course need "thermal" stages, where you had a cap on the amount of power that it could dissipate, but if you wanted to set your PC on a fan and cut out a vent you could move up.
I think that a standard needs to be set already. There is no excuse for making a handful of extra or different pins, or form factors off by a few millimeters just so that you can't build your own system or upgrade it.
I would hope that as time progresses you could put a faster chip on a smaller more advanced process into an older laptop, or just choose the exact graphics you want (IE less powerful) in a system with the processing power you need.

Unfortunately, the biggest reason for a lack of unified mobile GPU standards is that OEMs along with ATI and NVIDIA like to compete in a variety of ways. Look at Apple and imagine trying to tell them they their laptops need to conform to a standard layout.It *could* happen, and for higher performance laptops with discrete GPUs like the W90Vp, that would be ideal. In fact, the GPU modules in the W90 look very similar to the GPU modules from NVIDIA. The problem is, no one wants to do the work to make sure upgraded GPUs would work -- plus you need to worry about having not just a standardized form factor, but standardized heatsinks/fans.
Ultimately, a standardized notebook form factor would probably lose more customers than it would gain. Everyone would complain about the "boring design and aesthetics", and the number of new bugs/problems we'd see would probably skyrocket. But hey, maybe someone will prove me wrong on this and make the idea work....

Wait, NVIDIA managed to release drivers on all platforms simultaneously ONCE and suddenly they have a unified driver model? I'd have to wait and see if that trend continues down the road, but I'm not holding my breath.There's also the issue that a large number of notebooks simply won't accept the drivers directly from NVIDIA.

NVIDIA previously had a mobile driver program where they committed to quarterly updates, and they delivered on that three times (though the first wasn't quite "quarterly"). The drivers started out several months behind the desktop releases, and now we have drivers released on all platforms twice (185.81 and then the final 185.85) - though granted they're mostly the same thing.As far as laptops where the NVIDIA drivers won't work, are they in the "unsupported" list? They've worked on every laptop I've tried, which ranged from 8600M to 9500M to 8800M SLI to 9800M. What laptops specifically don't work or have problems? Or are these problems caused by old and cluttered Windows installs where malware or something else gets in the way?
If NVIDIA doesn't continue to release unified drivers, we'll certainly point it out, but at the same time they've already strongly committed to minimum quarterly updates. That's more than anyone else has done for mobile graphics.

Really impressive battery life. You can watch a 1080p movie on the road, as long as it doesn't last longer than 1h. Bah!
