Power Consumption

Part 3: Building A Balanced Gaming PC
By

Power Consumption

Rather than use our typical idle and Prime95/Furmark full load consumption data, for this series, we decided that the single most important number would be the maximum consumption seen while gaming. The highest consumption recorded was seen in GTA IV, but because the Radeon HD 4850 used in Parts 1 & 2 could not run this test, we instead chose to use Crysis.

Voltages were not pushed to any insane levels during our overclocking endeavors, so power consumption during gaming isn’t all too much higher than during the stock round of testing. The Radeon HD 5870 and 5970 stand out for their low consumption and outstanding performance.

    Its total nonsense, buying pc for gaming today. I have Xbox360 and PS3 + Nintendo DS and also QuadCore based gaming PC. I dont play on PC anymore, im only using it for browsing, listening music and communicating with others. Netbook should be totally sufficient for such task, i will never buy PC for gaming in future. GO and buy gaming console, if you have good TV, and you will be sitting around 2 - 2,5 meters from screen, graphics is pretty good - totally sufficient.


    if the diffrence bewteen console and PC isn't night and day, you must be using a 5450.

    I love how on the first page picture of all the games on this article show the games that truly take a toll on GPU's and CPU's. You are however missing Metro 2033 and Dirt 2 in DX11 which obliterates some GPUs in DX11!

    A metro 2033 graph wouldn't be interesting it would start at 0 and end at 5 for most set ups :D

    The choice of Corsair Dominator for the RAM is surprising, given that there are equally fast and stable choices at a much lower price point. OCZ, G Skill, Crucial, etc. I still love their power supplies though.

    They mentioned a part 4 in the article, with overclocking AMD processors.

    And where is the Core i3 530? This is the real gaming gem of a CPU, but I hardly see it in any reviews @ Tom's...

    Very enlightening though, given my current rig's specs, thoroughly depressing. Curse you for breaking my delusion that my PC was adequate! I feel an overwhelming urge to upgrade coming on.....

    A great article. I'm impressed with the I5 in all these charts. It would of been nice to use something a bit beefier than the i7-920 to see if that itself is causing a bottle neck.

    Wolfdale will still be a decent CPU until 2012, I guess.

    Where's i3, please include it in tests with same clock speed as E8400 and show its performance!

    I am very suprised that the quad core processors seem to give better results with the 5870. I wonder why that is. I still have my Q6600 OC'ed to 3.2...I was thinking that I should upgrade to teh i5 750...but after seeing this article...I am struggling to find a reason.....well unless I have a lot of money for a dual GPU card.....NOT.....;(

    so you guys claim we should be looking to buy a 285 (dx10 card) and a core2 duo 8400 (socket 775)? Exactly what are you smoking? yeah here go buy this 1982 ford mustang... its a mustang for crying out loud... its just the WORST mustang ever made. And its old technology so you could do a lot better by buying a newer one that will last longer and have better technology.
