~$800 Gaming Computer

I am going to buy this computer during the summer and I have an $800 budget.
I use this computer for gaming, surfing the web, MSN, editing videos, and watching movies.
I do not need a monitor, speakers, mouse, nor keyboard.
I live in Canada so please use , , or
I don't think that I need overclocking, but include it for the future I guess.
I don't really know what SLI or CrossFire is but I say CrossFire.
My monitor resolution is 1400 by 1050.
I want a quiet computer that can fit all my needs. But it has to be $800 or under.

I currently have these parts but I want to lower the price. I don't really know if they match or not because I'm a first time builder and I have a limited knowledge about computer parts.

CPU: Intel Core i5

Graphic Card: Radeon HD 5750

Motherboard: MSI P55-GD80

Hard Drive: Western Digital Caviar Blue WD6400AAKS 640GB 7200 RPM 16MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive

RAM: G.Skill’s Trident DDR3-2000

Case: COOLER MASTER Centurion 5 CAC-T05-UW Black Aluminum Bezel , SECC Chassis ATX Mid Tower Computer Case

Optical Drive: LITE-ON Black 18X DVD-ROM 48X CD-ROM SATA DVD-ROM Drive Model iHDS118-04 - OEM

Power Supply: Rosewill RV350 350W ATX 1.3 Power Supply

The total is around $900 and I need to lower the price down. Please help me revise this plan and fix any mistakes I made. If something doesn't match with something, feel free to tell me what I should replace it with.
Thank you! :)

    Not a great build. Pretty much everything in it isn't worth buying.

    Here's what I'd change:

    CPU: X4 955 $163. It's a lot cheaper and just as good.
    Mobo: Gigabyte GA-790XTA-UD4 $160 (if you want to Crossfire later) (really expensive up there. I'll find a replacement in a bit) or the Gigabyte GA-770TA-UD3 (with CPU) (if you don't) $244
    RAM: G.Skill Ripjaws 2x2 GB 1600 mhz CAS Latency 7 $109
    GPU: HD 5770 $165. It's a lot more powerful than the 5750. I believe the performance/dollar ratio is right around 1:1 from the 5750.
    HDD: Samsung Spinpoint F3 500 GB $57
    Case/PSU: Antec 300 and 430W PSU $100 (if you don't want to Crossfire) or the Centurion 5 and Antec Earthwatts 650W $130 for both
    Optical: Cheapest SATA DVD burner you can find $20

    Total: $804 with Crossfire, $695 without

    How much does $4 matter? I can try to find a different Crossfire board if you want to go that route.
