ASUS W90Vp: ATI Mobility Radeon HD 4870... with CrossFire

Power, Noise Levels, and Temperatures
For the interested, you can read the details on how we test power and noise levels. As you might expect, this is W90Vp consumes quite a bit of power, but it's not particularly noisy -- certainly it's a lot quieter than most gaming desktops. Temperatures on the other hand can get quite high, so you'll want to keep this notebook away from your lap if possible. The size of the chassis does help with dissipating heat, however, so it doesn't get quite as hot as some smaller notebooks.
Under full load, the keyboard surface ranged from 28°C up to 34°C, with most of the surface averaging around 30°C. The back of the keyboard (near the LCD) tended to be hotter than the rest, which makes sense considering the two GPUs, chipset, and CPU are located in that section. The left palm rest also tends to be a bit warmer, as the hard drives are underneath it. Temperatures on the bottom of the laptop range from 26°C all the way up to 43°C, with most of the surface averaging around 33°C. Again, the hotspots tend to be near the rear as well as near the hard drives. Exhaust temperatures reached 50°C on the rear and side. You will want to assure there's proper ventilation for the bottom of the laptop if you're planning an extended gaming session.

In the specs for this machine it lists an 8x DVDR drive initially, then refers to it as a blu-ray drive just further down - I assume the first entry should read bd-rom/dvd-r combo.I have to say the pictures are extremely disappointing as the main shots of the laptop are badly underexposed concealing most of the details. I do realise these machines are not easy to get a picture of but normally the pictures in reviews are pretty decent. It would be good to see some pictures with some standard items (DVD cases or something) when the laptop is open to get a better idea of the scale, I think the sleek look makes it look smaller than it is especially given it makes the D901C look small which I didn't think possible.
As for the laptop itself I did consider one of these mainly because the price was good but decided against it due to the size/weight. I had a Dell XPS 2 then M1710 and I think that's really the upper limit to carry around with me. I have an XPS M1730 at the moment and it never leaves the house as combined with its huge powerpack makes it quite a bit bigger and heavier than the M1710, there's no way I would go bigger again.
It's a shame to see the driver situation is so poor when the performance is clearly there, it's not very encouraging for other companies to pick up mobile ATI parts either.

Jarred (or anyone who may purchase this notebook), I have a different Asus laptop that has the same multimedia touchpad, and I did find a way to disable it. Go into the Mouse control panel, go to Device Settings, expand tapping, click on tap zones, and uncheck "enable tap zones".garydale - Friday, May 29, 2009 - link
Why is it so difficult to get good display drivers for games? The OpenGL interface is well defined so what's the problem with writing a driver for it that game developers can have confidence it will work according to spec.?Is this a case of the hardware manufacturers screwing up with the driver or the game developers trying to get around the API to work directly with the hardware or a bit of both? Frankly, I don't care. If I want to play a game on a computer, it should install and work just like any other piece of software or hardware.
Hopefully AMD/ATI's release of details of their API will help bring stability and performance, at least for Linux games. Now will NVidia follow suit and allow the open source community to build their own drivers to end this proprietary "buggy driver" lunacy?

I believe most of the driver updates are to optimize the way the GPU executes certain code. In theory, the drivers should run all code properly but not optimally. The reality, sadly, is that the "properly" part is only correct about 80% of the time with new titles. Add CrossFire into the mix and that seems to drop down to 50%. If you have a regular dual card CrossFire setup, disabling CrossFire in the CCC often solves compatibility issues, but that's not an option on the drivers I've received for the W90Vp.In the case of Empire: Total War it looked like the drivers were rendering properly on one card but not on the other. If I grabbed a screenshot via the PrintScreen button, everything looked correct, but looking at the screen only the landscaping and sky were always visible and correct. The units, trees, buildings, etc. were only visible about 10% of the frames, which pretty much means you can't play the game.

I own one the W90VP-A1.I have been dyingto update the drivers, it sucks running on OUTDATED drivers :(

If these are simply mobile desktop replacements why doesn't somebody get on making a desktop built into the screen already?And I don't mean the hideous monstrosity that is the Dell XP1.
I am all for laptops, but this form factor is silly above 15.4" in my opinion.
(that said, I love the tech, it is very cool.)

Dunno if you've been asleep for the past two years but just about every major PC manufacturer offers a desktop built-in to the screen nowadays, none of which are "hideous" (strictly my opinion, but I find it hard to find a screen "hideous", and that's essentially all these offerings are is a screen).garydale - Friday, May 29, 2009 - link
It's generally cheaper and faster to run multiple desktops in the locations you need than to lug a "desktop replacement" around. Just keep your documents (and other settings) on a USB key or implement an Internet synchronization scheme.The simple fact is that you cannot get anything that can be reasonably called a laptop to match the performance of a desktop. Laptops don't have the space for multiple drives, they can't dissipate heat as well, and they certainly can't accommodate expansion.
To get the same performance of a desktop in a mobile platform, you have to wait for the technology to become available then pay a premium for the privilege. People have been saying laptops are getting near desktop performance for decades. What is actually happening however is the price of admission for an application platform has been decreasing.
You can get a resonable desktop today for what a hard drive would have cost you twenty years ago. However, if you want cutting edge power, you need a desktop or larger.

The charts are technically labelled incorrectly. I believe for instance the first chart, black bar, means the ratio of nVidia performance to ATI, not percent improvement as it is labelled. Saying "102 percent improvement" actually means that the nVidia solution is twice as fast as the ATI, which from reading the rest of the article appears not to be what the author meant. The rest of the charts are labelled in this way also.
