    And if you go to the two next page you will notice that that the 35W TDP CPU consume about 7.6W less then the next CPU under heavy load, the thing is that it take longer period of time to execute the benchmark test.

    Only total power consumption to complete same task in Watt-hours is important. Maximal power consumption doesn't matter.

    "If you want to waste your power on heat production (which is what the TPD and the PSU efficiency represent) and cooling it down (which usually involve making noise), that fine with me."

    TDP is not an indication of heat. Why is Ivy Bridge hotter than Sandy Bridge? Same for the PSU; if it overheats, you and your case really suck.

    Price seams a nice bit below the windows variant: http://www.dell.com/us/p/alienware-x51/pd

    Then why did you point to energy needed for the idle and low load to counter the average power consumption ? Cause it make no sense considering you latest argument.

    And remember that at the start start of all this I was speaking of power efficiency, not performance, has I was comparing a 55W TDP 2.7Ghz celeron, which to be about the intel product you can get for about $50 (since he was suggesting a pentium, but they start around $65), to a $75 35W TDP 2.6Ghz Pentium, which I think was more worth it if you were trying to save money, for a lowest end gaming PC, has it would more then likely consume both less energy while idle and under load.

    The best really depend on whatever you spend most of system spend most of it time in idle/low load or in heavy load, which most home computer don't, including a gaming PC, has it most likely see it fair share internet, video and lot of game that are mostly GPU load not CPU. So I am mostly always gonna suggest the higher priced lower TPD CPU over the lower price higher TPD CPU of somewhat close performance, and if the guy got real money to invest, suggest undervolting the best cpu he can buy instead, if want to save power. (but that last case don't really apply when speaking of Celeron and Pentium =p)

    Never said indication of heat, I said it was power wasted on heat production. TDP is an indicating of power dissipation, you know what create power dissipation in a electrical circuit, a resistance, which dissipate power by creating heat . Want to see a device which duty is power dissipation, look no further then your toaster.

    From Alienware's site:
    With an available built-in firewall and virus protection, you can surf freely and safely with Ubuntu.
    Virus protection on Linux? What's that for? And does default Ubuntu actually include that?

    With over 25 gaming titles available
    I'm pretty sure it's much over 25, unless they are not counting indie games.

    Yeap, pretty much. I have a GTX 660 as well, and it just barely runs the latest beta of Expeditions: Conquistador fluidly. It's like 50 FPS on the overworld map while rotating the screen. It also doesn't handle the new Unigine Heaven: DOF Everywhere too well, with 32 FPS being the average.

    Yes and no...

    What's good is that, for once, we can compare real prices, and compute the price of Windows pre-installed.

    But then, as usual, it is a scam (for high end machines)

    1st configuration : Ubuntu is 100$ less
    2nd configuration : Ubuntu is 50$ less due to the "savings" on the Windows model
    3rd and 4th Ubuntu configuration don't have the equivalent Windows configuration.

    But we can see that the 3rd configuration for Windows is the same as the 4th Ubuntu config, but with a 2TB disk instead of a 1TB, and at the same price due to "savings" -200$- again on the Windows config.

    So, scam again... because if you need that 4th Ubuntu config and have 1049$ to spend, you'd better buy the Windows version and remove the useless O.S. (or get it refund if your country laws allows -France for ex.-) because you get an extra 1TB of disk for free.

    As already said above, good gesture from Dell, but we expect better... or should we from an enterprise that accepted a big "loan" from Microsoft?

    P.S.: note that all these Windows config are advertised with Windows 7. Glad to see how W8 is successful!

    Well, they do need to address existing concerns of customers who will be buying that, namely the Windows bunch. It's real worry on Windows, so naturally people would be asking "and what about a firewall / virus protection?". Since it's handled for them in Ubuntu, they can mention it is "included". Otherwise, you'd get a ton of people asking the same question...

    Mentioning that "it's not even needed in the first place" would have an even better effect...
