Power, Heat, And Efficiency
We mentioned earlier that the 1,000W power supply was probably a bad choice, since the 850W version was cheaper and had a higher efficiency rating. Let’s see how far overboard we went.
At our maximum overclock and with an unrealistically high load of three threads of Prime95 and with the fourth CPU core dedicated to FurMark's full-load graphics test, the overclocked configuration consumed a mere 879W from the wall. At our power supply’s approximate 82% efficiency (see chart), we really only needed a power supply with around 720W capacity. Thus, the super-efficient 80 PLUS Gold rated Corsair CMPSU-850HX could have been a great choice while providing enough extra power capability to support future upgrades.
Heat change from overclocking was minimized through increased fan speed.
With an average performance gain of 17% and an average power increase of 20%, the system loses 2% overall efficiency.

5870s next SBM? Bring it on!
I'm aware that a comparison with the last high end SB PC would be misleading as it, basically, didn't work properly, but nonetheless it would be nice to see something to put the performance into context.
Looking at the benchmarks for fallout 3 and world in conflict, the 1300$ pc from a few days ago is not that far behind. (pretty close when o.c'ed)
what really pisses me off is that tomshardware guys always seems to try to make it exactly 2500~ and they sometimes put some things that isn't needed like Antec 0761345-75018-9 "SpotCool" LED Fan and an NZXT case for such a budget ?!!! i think they should rename the title to maybe 2000$-2500$ so that they don't put unneeded things to just make it the exact price do anyone agree?
Im really suprised that all fit i personaly wuold have opted for a better case why dident they choose something like a coolermaster sniper ..... and then they wouldent have to buy that spot cooler thingy and still have 2500 XD
I am always 'concerned' by watercooling that has no reservoir. With the Panzerbox the radiator location is in the very top of the case and would surely end up as the 'reservoir' , collecting any air that built up over time ?
Would a pump and reservoir (sealable type) fixed to the case floor work for air collection (something like the Thermaltake Prowater ones) or, would air continue to migrate to the radiator regardless ?

I think they should just build the performance machine for raw power. LED fans and Daft cases are a matter of taste or lack of.
So the price of these machines isn't the limit. It should be the average FPS / cost. or what ever value per cost that is the focus of the test.
