Building computer 1000-1200

[powerfuel]

APPROXIMATE PURCHASE DATE: I don't care (the closer the better but I can wait if really there's something that worth it) BUDGET RANGE: CA$ 1000-1200 (Big max 1400)
SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Mostly for gaming, Multimedia and Work
PARTS NOT REQUIRED: keyboard, mouse, monitor, speakers
PREFERRED WEBSITE(S) FOR PARTS: no idea
PARTS PREFERENCES: CPU - intel
OVERCLOCKING: Yes
MONITOR RESOLUTION: not included in computer price. I'll go with what is currently needed on market.

I have already checked for some CPU: the E8400 http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=3574211&Sku=CP1-DUO-E8400 and the i7 http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=4240166&Sku=CP1-I7-920 seem to be both nice CPU for what I need.
Otherwise, I'm completly lost for other parts.
Random question: If I'm overclocking my CPU to (example) play on Crysis, after (IDK) like 20 mins I'm tired and I want to hear some music. Can I bring back the CPU to his normal clock frequency without restarting or whatever so it'll probably run quietly?

We need to know your monitor resolution in order to suggest an appropriate graphics card for the build. I would really suggest an AMD build, you can fit a quad in that budget easily along with a powerful graphics card to help you out.

IDK what's needed now for video game. Keep in mind that my monitor isn't included on the computer price. I'd go with a 512mo maybe higher...?

If you want... Actually, I need some idea. I think I can find some but I was wondering what is the currents configuration for a "normal" gaming computer. I've done some research and the i7 920 seems to be a good CPU to OC but some tell me that AMD is a good choice b/c of their low OCer Quad prices(black edition?).
