Sorry that I took so long to reply... but my quad core that I made for ~$850 sans monitors, I did by semi-patiently looking for deals/rebates on slickdeals.net.

- MSI Nvidia 8800GT 512mb - 239.99
- Intel Q6600 G0 stepping 2.4ghz - $277.00 (no deal there)
- http://www.clubit.com/product_detail...temno=A1306233 - Case - $65 - $50 rebate = $15
- Gigabyte GA-P35-DS3L Mobo - $88
- http://www.zipzoomfly.com/jsp/Produc...tCode=10006237 - Coolermaster 750W PSU - When I got it, it was $99.99 - $50 rebate = $49.99
- OCZ 4gb (2x2gb) RAM - $109
- Seagate Barracuda 250gb - $69
- Cheapest DVD-burner/rom - $23

Total - $870

I also eventually got an aftermarket CPU fan/cooler so that I could overclock, adding another $23, but i didn't count it as its not necessary.

If you're in no hurry, browse through slickdeals.net every day and look for deals on individual parts.
