Power Consumption
We measured "platform" power consumption at the wall outlet using a Watts Up Pro power meter. We do not include the power numbers for a monitor or external speakers; however, we do install a set of headphones in the audio out jack. We also turn on all peripherals in the BIOS along with enabling all power saving features in the BIOS. We measured idle power consumption after 15 minutes of inactivity and the average power consumption while running the Canyon Flight benchmark in 3DMark06. Power management is set to "Balanced" mode and the prefetch folder is cleared for each test.
At idle, Windows XP Pro x64 has the lowest power usage in both single card and dual card operation. Under load, Windows 7 has a very slight advantage compared to the other operating systems. However, there are no real differences overall between Windows 7 and Vista.

I have the W7 Beta, and it wouldn't install off of a SATA Optical Drive onto a PATA HDD.Weirdest problem I have ever seen, couldn't even see the Optical drive once 'windows' the (pre-installation environment) had loaded.
I guess I needed to load RAID drivers? Seems annoying to let it boot the install without drivers, and then hang when attempting the install off media it just booted from.
It isn't "Terrible", but it ain't quick neither. I hope it gets better, but it still doesn't have the lean and mean feel of a good fresh 2000 SP4 install, or even XP SP2/3. (dual core 2.4Ghz 2GB DDR2-800 8600GTS)
Maybe I need an SSD?

Random question from an XP user. ;)I mostly like RC1. I was able to customize the UI enough to be mostly satisfied with it, except for one setting.
In XP, when you navigate the Start menu folders, the different folders cascade from left to right. Example: Start > Programs > System Tools > Backup. You know the drill.
In RC1, each folder overlaps the previous, and you have to use forward/back buttons to backtrack. I find this annoying actually. I prefer XP's workflow. Is there a setting where I can make the folders function like XP?

Thanks for the excellent article guys, covered practically everything I wanted to know about the RC before taking the plunge myself and formatting my hard drive for the install.Cheers!

"Multiple GDI applications can now issue commands to it at the same time, and this is all pushed off to the video card to be its problem."I'm pretty sure this means that alt-tabing from a game to desktop will be quicker. :)

It's all good, but Windows XP x64 is not an XP. It is based on Win 2003 Server core and share's the same updates (so there is no Win XP x64 SP3)It doesn't reflect the real XP performance and it's not that good from compatibility view. The most common OS switch would probably be Win XP x32 -> Vista x32/64 ?-> Win7 646432/64

Anyone know how to get hardware accelerated video decoding in windows 7. I've gone through a couple guides with no luck so far.brian26 - Wednesday, May 6, 2009 - link
Seriously, fuck off with the apple loving bullshit. Mac os isnt competing against Microsoft, if they did they would have their asses handed to them by the mass public complaining nothing works. They build their os for a specific set of hardware.. thats like making a fucking Operating system for a console. Until they have the balls to step out and compete against Microsoft in the OS department and drop their over priced proprietary bullshit then they can fucking burn down for all I care. So stop putting them on the table like they even matter. Its been 5 minutes you better go fucking check to see if steve jobs is in the hospital again hadnt you bitch ?strikeback03 - Wednesday, May 6, 2009 - link
You're late - the people claiming Anandtech has a MS bias got in on the first few pages of comments.Lexington02 - Wednesday, May 6, 2009 - link
He is not late, he is claiming otherwise to the other people who think that Anandtech is MS loving while this dude is claiming to be Apple loving. I wonder, which is true... Apple lovers or Microsoft lovers...Lexington02 - Wednesday, May 6, 2009 - link
