Gaming Computer - Build Critiquing

Hello,

SSo, I have a build for a gaming computer I'm looking to buy really soon. I plan on purchasing all the parts by Monday of next week.

Here's my wish list of parts I will be purchasing.

http://secure.newegg.com/WishList/PublicWishDetail.aspx...

So now I'm looking for build advice. If you feel anything is wrong with that build, you can change it up and post it back, but I really want to stay below $1500, including shipping costs.

APPROXIMATE PURCHASE DATE: Within two weeks. BUDGET RANGE: No higher than $1500

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming, movies, surfing the Internet

PARTS NOT REQUIRED: Keep the parts in the wishlist. Keep the keyboard, mouse, and monitor I chose.

PREFERRED WEBSITE(S) FOR PARTS: newegg

PARTS PREFERENCES: I prefer Intel CPUs. I was told the i5 will do great in this build, so maybe we can work around that. nVidia or ATI cards will work. I don't mind.

OVERCLOCKING: No SLI OR CROSSFIRE: Maybe someday

MONITOR RESOLUTION: 1920x1080

ADDITIONAL COMMENTS: I would like a PC that can run the new high end games that have been coming out on max setting and with a good frame rate. This build looks like it will do it, I think, but any input will be great. I want to have decent airflow so nothing overheats and I also want to make sure the card I have will fit in the case. I hear these new cards are really big. I also want to know if 750W is overkill for this system. I heard I could step down to a 650W.
