I5 Budget gaming build (Approx $1100 CDN)

Hey all, this will be a first time complete build for me, any suggestions on the proposed build are appreciated. I started with some basics that I wanted and scavenged the rest from some ofter builds on this board.

APPROXIMATE PURCHASE DATE: Within the next week BUDGET RANGE: $1000-1100 CDN before rebates

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming, Work use (primarily office), Surfing the net

PARTS NOT REQUIRED: Monitor, Hard Drive (Reusing a Seagate 500gb), Optical drives (Reusing), Keyboard, Mouse, Speakers

PREFERRED WEBSITE(S) FOR PARTS: newegg.ca COUNTRY OF ORIGIN: Canada

PARTS PREFERENCES: No brand preference

OVERCLOCKING: No SLI OR CROSSFIRE: Maybe

MONITOR RESOLUTION: Currently 1280x1024

ADDITIONAL COMMENTS: Willing to increase the price a bit for good performance gains or quieter parts. I have no idea on what to do for a case, a mid size ATX should be fine for my needs. I am not planning on doing crossfire to start due to the cost but it is something I would consider for a future upgrade. If I am missing anything important please let me know.

Thank you for any suggestions that you might have.

^ Hi...thats a good setup...
I do have a few suggestions...

1. Get this CPU + Mobo combo...
The mobo is as good as that UD4P and this combo saves you CAD 10

2. The HD 5850 is a serious overkill for your resolution...Why not check out the HD 5770...It is as powerful as the HD 4890 and is DirectX 11 and would easily max out any games for your current resolution...
So when you upgrade your monitor, you can add one more in crossfire, and that crossfire performance can even match HD 5870 or maybe even better...And its price is sure to come down when cards from Nvidia come out...

Rest of the components are very good...

Might as well check out directcanada.com, ncix.com they have very good deals and free shipping and people say directcanada.com dont charge PST

The 5770 is not as powerful as the 4890, it just about matches a 4870. Great for 1280x1024. May not be as happy if the monitor gets upgraded to a widescreen LCD.
