$800 budget gaming/work PC.

Hello, my old PC is dying on me, and after about $200 dollars down the hole it is pretty obvious that this old computer is not salvageable anymore. So I figure might as well get a new PC.

LOCATION: Canada

BUDGET: $0 to $800 ($200 dollars reserved for new monitor)

APPROXIMATE PURCHASE DATE: Next week or two

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: gaming/multimedia, work

SPECIAL PREFERENCE: Trying to build it as silent as possible. (for watching movies and leaving it on during night in my bedroom).

PARTS NOT REQUIRED: keyboard, mouse, speakers, harddrive, OS

PREFERRED WEBSITE(S) FOR PARTS:Canadacomputers.com, NCIX.com, directcanada.com

OVERCLOCKING: Probably limited to graphic card only.

SLI OR CROSSFIRE: SLI preferred if possible, but not too important. I have a 9800GT and would like to salvage it if possible, as it will cost me $20 dollars to return it.

MONITOR RESOLUTION: Currently looking into 1600x1000 monitor or possibly a 1920 x1080 capable monitor.

ADDITIONAL COMMENTS: Location is Ottawa Canada, so unfortunately can't use American stores.

Any help would be greatly appreciated. I know the basics but is a complete newbie on determining hardware performance/cost ratios, component bottlenecks, temperature and noise, etc. I have already made couple of hardware buying mistakes when I tried to revive my old dying PC, so want to get this new rig just right.

Thanks.
