I am taking the plunge and have decided to build a system for the first time. I have been using pre-built Laptops for the last 5 years, so my knowledge of what is going on inside desktops is definetely dated. I will be using this system to edit 1080P HD videos and play current games. I have switched up my selection no less than 100x, but below is what come up with to date. I know some parts the Case and the PSU may be expensive for a $800 build, but I wanted to pick ground work components that could last many future upgrades, instead of putting money towards the components that will become outdated quickly. Please take a look and make sure I am not making any mistakes. Everything after rebated, taxes, and shipping comes to about $850.
I thought about the Q6600 as well, but was unsure as to if I would need it. I figured I could save $80 now by going with the E7200 and then down the road purchase one of the 45nm quad processors in a year or so when those prices have come down.
