Help me pick parts for my new computer, especially the processor, fans and motherboard!?

I know I've posted about this before but this time I'm seriously about to buy the computer. I really need help picking the processor, fans and motherboard more than anything. I'm considering buying from pcusa.com but am open to others if it's cheaper or with better parts. I'd like to buy it already built (I'm not good at putting things together).



I want a very fast computer that will handle family video editing and gaming. I'd rather spend a bit more now than have to upgrade sooner, but I'd also like to spend around 800 dollars or less. ** I do not need a monitor, speakers, mouse, or keyboard. I do need an operating system.



Here is an idea - feel free to comment on the parts I've chosen, but the processor and mobo choices I made are pretty random - I'm not familiar with their quality.

Processor - Intel Quad 2.43 GHz

Fan - corsair or coolermaster 550 watt (modular if available) {don't choose psu less than this, that's minimum requirement}

Motherboard - Nvidia Nforce 750i (sli - expensive) or 730i (cheaper)

If you don't want to upgrade very soon then you should think about an i7 prossesor with DDR3 Ram. It is super fast and futureproof.
