I need some help filling in the blanks

[GoneTooLong]

So I recently broke up with my girlfriend and the only things she took was the dog and the computer. So its time to build a new one, but its been a few years since i've done it and I have no idea where current tech is. So i'm coming to the gurus for help.

Approximate Purchase Date: e.g.: Two weeks

Budget Range: $600-700

System Usage from Most to Least Important: Gaming mostly, wandering the internet

Are you buying a monitor: No

Do you need to buy OS: No

Preferred Website(s) for Parts: Newegg

Location: Tampa, Fl

Parts Preferences: None

Overclocking: Maybe

SLI or Crossfire: Maybe

Your Monitor Resolution: 1680x1050

Additional Comments: I already bought a 128Gb samsung 830 ssd to use as my boot drive

Why Are You Upgrading: I want to play borderlands 2

This is what i've come up with so far.

With your budget, you may want to take overclocking out of the question to squeeze in a few more $$$ for a good GPU. I'll make a parts list

This brings you a little over ~$50 overbudget when you buy online

Here's another rig I made that will perform just as well, if not better -

The i3 will hold you back in some titles such as Battlefield 3 Multiplayer, however. But it's still something you may want to consider.
