While I appreciate Proximon's and skora's comments, and this build does add more fodder to the "index," I really didn't like it. For starters, gaming is not likely to be the only thing done on any PC. Four GPUs precludes the possibility of adding a tuner, [fax]modem, or anything else. Since there is also the matter of diminishing returns on Crossfiring four GPUs, my alternative would have killed two birds with one stone, using three GPUs with coolers that exhaust their heat (e.g. HIS or XFX), leaving a PCI or PCIE X1 slot open. In addition to getting three with better coolers, the cost savings of one less GPU would probably have allowed a CPU upgrade to a 955BE.
I do hope this build helped the Intel fanbois realize that for GAMING, an AMD system can provide visibly equivalent performance, and that the AMD fanbois will finally sit down and shut up about PRODUCTIVITY performance.
