the budget is $900 so an i7 is out of the question
i have choose to go with 955 build.
heres the parts i have picked out. but i am quite unsure which ram kit to get, also at a loss for video cards as well. This pc will be used for gaming majority of time, along with some video editing, i hope it will last for the next 4 or 5 years w/o upgrade.
@ 1920x1080 a HD 5770 will be a good choice.
The HD 5850 would be a nice upgrade, especially if you're not considering a Crossfire HD 5770 in the future.
If you can cancel that Zalman 9700LED purchase - go ahead and do so.
It's not that great an improvement over the stock AMD cooler. FrostyTech showed these cooling (rise above ambient temp) and noise level measurements (dba):
Zalman CNPS9700 LED 16.5 degrees 56.5 dba
AVC Z7U7414001 17.0 degrees 63.0 dba
