The processor is fine, putting in a video card won't effect it at all. You could also upgrade the processor if you want but it is not a trivial task especially when it's soldered directly to the motherboard.

The connector that holds all the pins straight broke off the motherboard.

This is what worries me. There is no telling what kind of damage has been done without looking at it for myself. I'm assuming the connector simply broke away and everything else is fine..but who knows.

It might be possible to repair the motherboard by re-attaching the connector. The problem is you'll have a very hard time finding someone that'll do it for you locally. "Repair" shops will just tell you to buy a new computer and claim it's not fixable. What it boils down to is hardware is so cheap there is no point in patching something up, hence why guys that can solder don't work in most "computer repair shops".

Anyway if you decide to put in a video card heres a good page on what you'll need to do to disable the on-board video: http://www.wikihow.com/Disable-Onboa...-Your-Computer

Keep in mind that they assume that you still have working on-board video. In your case you'll just have to hope that;

- You can disable it with a jumper

or

- The computer will automatically prefer the new video card and allow you to turn the on-board one off in the BIOS before booting into Windows.
