Bang for your buck Gaming Rig $600-$1000

I am a bang for your buck guy. I don't need the fastest but would like to squeeze as much gaming performance out of the money as possible. I have not overclocked a system before, but am willing to spend a couple hours doing it if it yields tangible performance gains. IE: I don't care if a game goes from 90 FPS to 100 FPS. As long as the minimum is 40 FPS + I think I am good.

Approximate Purchase Date: Now to a month from now. (I'll actually be making two systems, but one this week and one a month from now or so.)

Budget Range: $600-$1000 ; instant rebates are good but don't care for mail in. Also I don't need to spend the max if I can get performance I want for less.

System Usage from Most to Least Important: Gaming, Graphic Design/Layout(Photoshop/Illustrator), Video Editing(Record/Stream game play), other things as well but just about any rig will do all of that just fine.

Parts Not Required: Monitor, Keyboard, Mouse, Speakers.... All I need is the box and innards. Might even use old Antec cases I have.

Preferred Website(s) for Parts: In order; Newegg.com, PCDirect.com(local store), Amazon.com

Country: United States

Parts Preferences: Was AMD CPU person but Intel appears to be the way to go. Prefer EVGA/Nvidia video cards but open to others. Been using Cosair PSU but open. RAM 8GB+ don't care much about brand.

Overclocking: Maybe

SLI or Crossfire: No

Monitor Resolution: 1920x1080 or 1920x1200

Additional Comments: Need to have SSD 120GB-260GB for main drive. I have one or two SATA HDDs I'll put in as well.

Main goal is to be able to run a game like BF3 with max settings at 1920x1200/1080. I don't need AA of AF cranked. I expect video card performance to be GTX 560TI or better to get what I want. I am open to AMD video card, but thought I may want to stick with nVidia for CUDA with my Adobe software.

I expect the CPU to probably be i5 2400 or better. From what I can tell the only reason to go to i5 2500K is if I am going to OC. Will i5 2400 + GTX560TI be enough to get great performance in games that I want at that resolution?

Just want to make sure I am not missing some awesome deal somewhere right now.
