Power And Heat
If the price tags on the $1600 and $2400 systems weren't already high enough, their power consumption figures might put your electricity bill over the edge. Of course, a straight value calculation is rarely the basis most enthusiasts use to make their purchase decisions, but I still get a kick out of showing how well sub-$1000 machines perform given their cost.
Paul and I are a little dubious of Don's 2°-above-ambient idle CPU reading. Perhaps he measured right after booting up?
The only two exceptional temperatures come from the GPUs in the overclocked $1600 and non-overclocked $2400 PCs. I used a custom fan setting to force my overclocked build's graphics temperature way down, although it resulted in a significant increase in noise.
The first one I can think of, being kind of boring as it might be, its the most obvious one to have: loading times. There are games that load a bazillion things on the fly and are some-what storage sensitive (MMOs basically) and we all hate waiting for everything to load, right? It can be clocked with a 10% error margin (thinking it usually takes around 200ms for human response).
I'm asking this, because RAID0 could become important if we see the value it adds to our builds. I know they're nowhere near SSDs, but Steam + other games take a LOT of space. My own Games folder racks up 410GB, where Steam is 300GB alone. You could slap 2x500GB HDDs in RAID 0 for half the value of a 240GB SSD if memory serves right and 2x1TB HDDs are just a tad more expensive. You can even use notebook HDDs if you want, haha.
Also, I would have cut the memory by half and remove the SSD for getting these 2 cards. Also... you really needs to change your SBM... it is ridiculous at this point.
