I'd go with the i7 930... unless you're overclocking theres no reason to get an aftermarket heatsink/fan or thermal grease.
The factory heatsiink that comes with it will be fine for stock clocks, and already has thermal grease ready to install.
You want 3x2gb sticks (6gb kit) - whichever is a name brand that has a good rebate/combo package.
Samsung spinpoint's are great value... 500gb or 1tb
System will be spectacular once you get a GTX460 in there
thanks. I am thinking of getting i930 as well. Thinking about getting an OEM with Heat sink because of the small price difference. You can click on the link and see. Only thing I worry is the size of the heat sink. Could it be a trouble for my Motherboard or my case?
