Well, the Pentium D 9xx series processors are nice, but if you want something better, get the Athelon 64 X2 series CPUs. The Pentium D's use a quad-pumped FSB to communicate to each other, so in terms of processing, the Pentium D 9xx processor is not as good as the Athelon 64 X2. I would go with AMD on this build, if you want a gaming machine, AMD is what you want. If you want a gaming machine, but at a lower cost, go with intel. Either way you'll end up with a good machine!
