Application performance is basically what you would expect of the Core i7-720QM, with the exception of the DivX encoding result. We're not quite sure why the G51J scored so poorly in that test (possibly a software issue due to the switch to Win7), but the x264 and CINEBENCH results show that the gap shouldn't be that large.

PCMark05/Vantage also show a large advantage to the other high-end notebooks, but the Clevo and AVADirect systems have SSDs and that accounts for a large part of the difference. We've shown in other articles that Win7 tends to improve scores in PCMark Vantage by a noticeable amount, and it's a difference you can feel when using a PC. This results in the G51J actually beating the M980NU by a decent amount, though here the i7-720QM is already on par with the QX9300.

Finally, we have a few results from the ASUS G51Vx-A1 (Q9000 system) in PCMark. The older 2005 version has the G51 laptops essentially tied, while PCMark Vantage gives the G51J a large 28% lead. However, the G51Vx also shipped with Vista, so much of that difference is due to the change in OS.

Overclocking of the G51J shows the expected 5% increase in performance in the multi-threaded tests. As noted elsewhere, we actually saw lower performance in PCMark (and games) with the Turbo mode enabled, so most users will be best to leave that setting off.

If you need a fast mobile computer, the G51J will get the job done, but we can say the same of virtually any high-end laptop with a quad-core CPU. If you're doing tasks that really stress the CPU and can benefit from a ~25% reduction in the amount of time required to render images or process videos, something with an i7-920XM might be a better idea. Then again, upgrading to the D900F with its desktop CPU would be the best bet for maximum performance: it's nearly twice as fast as the G51J in x264 and CINEBENCH.

    Sorry... I didn't think to test the mic. Built-in mics range from passable to lousy, so any time I use a mic I use a headset.

    I commented on the first article that seemed to have an odd layout (conclusion on the first page, etc.) so it's only fair that I chime in with an update. This one was much better! I liked getting the introduction, then an overall opinion on the next page. Kudos for also providing a quick link to view the technical details of the laptop as well.

    Not having both laptops at least on the same page if not the same graph for the performance benchmarks was a weird choice though. I realize they are in completely different leagues, but still an easier comparison between the two would have been nice.

    The games are all run at completely different settings (for obvious reasons). 3DMark06/Vantage also run at 1280x768 on the lower spec laptops, unless you connect an external LCD. Since they all run at that setting I've kept the results. I thought about combining everything, but I've got two sets of spreadsheets with results: one has the high-end stuff and the other has low-end options. Putting together all the charts already takes forever and a day, and combining them all would potentially increase the time and just make the charts more confusing. (I'm still not sure I did the right thing on the last few charts where I combined results.)

    my powerplans never mess up. never did on vista, never do on win7. but i never install specific powerplan-tools, just a clean os install, and then let it be (and reconfig the power plan, like the password-after-standby and such).

    so far, i haven't encountered your issue on all the machines i've tested.

    weird.

    It has happened to me fairly often since I did a clean install of 7 on my Desktop PC. Password on resume, hard drive timeout and monitor timeout are the ones that get reset for me.

    Just put SetPower on it (google it). It lets you configure the power settings based on time of day and takes into account whether the machine is plugged in or not. It uses scheduled tasks so it doesn't consume resources other than when it is switching plans for you.

    I have on the other hand ran into them quite often, especially on my laptop. I have the opposite problem - the damn thing just won't stay asleep and often I wake up finding it's on even though the lid is closed. And if it's not plugged in, you can imagine what kind of charge is left in it. I was getting it in Vista and I'd say it's probably even worse in Windows 7. I am guessing it has something to do with Microsoft's implementation of DLNA, I mean access to multimedia libraries and streaming. Microsoft specifically talks about devices needing to be able to wake up remotely when queried. That's all fine and dandy and even desired in a desktop but a laptop should really be a special case. Especially once the lid is closed.

    I have issues too, with and without clean installs. Sleep sometimes doesn't even trigger. Screen goes blank, screensaver, even though I turned it off. Very strange behaviors in Windows 7. This is for laptops though and I have not encounter anything with deskstops. There are other various strange little quirks in Windows 7 as well.

    Most annoying thing is the windows explorer restarting itself. I think I figured out what's been causing this problem and have since accidentally fixed it. Its was one of the codecs with the k-lite codec full package that was screwing things up. Bastard. None of the tricks via Google worked for me except for this.

    I'm guessing that it's possibly linked to the OEM software. Still, I'm 99% positive I had it happen with the Clevo W870CU and a clean install of Vista. I know on an Acer system I uninstalled every piece of software that was loading at startup, along with removing/disabling some services, and it STILL happened. Gah! I also don't like how many OEMs limit your setting on the critical battery percentage to 5%... I had to manually hack that on the G51J to make it 1%.

    At any rate, it was something I've encountered enough during the past couple of years that I finally wanted to mention it. ASUS on the UL80Vt is particularly annoying if you use the button on the keyboard (the ExpressGate "power" button) to switch between plans, as it will jack with all sorts of settings. To my knowledge, there's no way to edit the defaults that it sets on most of the plans (i.e. the Power4Gear Battery Life option will turn on "auto-hide taskbar" every time you activate it).
