Power And Temperature Benchmarks

At stock speeds, the $1,500 Core i7-920 system uses relatively little power and is in the same league as the $1,000 Phenom II X3 720 system. But when overclocked, the Core i7 machine is significantly more power-hungry. The overclocked/core-unlocked Phenom II X3 720 build doesn't really require a tremendous power increase over its stock draw, but it does consume more.

The $1,000 system's temperatures remain quite low, even when overclocked. But the $1,500 machine's components do appear to build up a lot more heat, especially when overclocked.

    When you say SBM: Enthusiast System, I am expecting this to be more than just another gaming rig. You may have your own reason for sticking to a Phenom II x3 720 and HD5830 crossfire but I believe a Phenom II x4 955 and HD5770 crossfire would make more sense or more well-balanced (instead of trying your luck by unlocking cores). In fact, we could also grab a HD5870 and downgrade our mobo a little and that would make a truly well balanced enthusiast system.

    Nice CPU choice you morons. My grandma could build a more balanced system.

    I'm with one-shot, 6core AMD for $200 can't be beat.

    It would have been nice to see the PII X6 1055T with a moderate downgrade in GPUs to afford the higher cost of CPU and motherboard. The i7 embarrasses the PII X3.

    I find it surprising that you are always successful in unlocking the 4th core

    not a fan of the 5830's or the 720 cpu choice is all.

    Would have rather seen a dual 5770's or a 5870 with a i5-750 or a 955

    games more and more are using cpu for doing things. I also tend to use a comp for other things more then games.

    A phenom II 955 BE:160$+2 Xfx hd 5770sfor320$+GIGABYTE GA-890GPA-UD3H for 140$=620$ would certainly have been a better choice than your 670$ for CPU+GPU+mobo.

    A Thermaltake V3 instead of the Antec 300 would have saved you $15
