Is this a good selection of computer parts?

I am planning on building a computer, and i have a 700 dollar budget. I’m planning on using it as mainly a gaming computer, but I also do a little video editing. I am going to hook it up to the HDMI on my TV to save me the cost of buying a monitor. I already have everything picked out, but I was just wondering if I could maybe improve this list. Here is the list of items I am getting:

I have an ATX Mid tower case, a decent ATX motherboard with a 2600MHz FSB with a Firewire port, a Quad Core AMD 3.4GHz CPU, two DDR3 2gb (4gb total) 1600 speed RAM sticks, a 500gb SATA hard drive, a DVD/CD reader+writer, a 550 watt CPU, a wireless keyboard+mouse, and a webcam. I know it seems like a lot to do, but if anyone could help me ‘edit’ my list, it would be a tremendous help. Also, I decided not to get a graphics card for now (unless its ABSOLUTELY necessary) because I just don’t have the money to buy one. If anyone could suggest one for future reference, that would be great. Thank you so much for helping me out if you can.
