I5 Sandy Bridge vs i3 Ivy Bridge vs AMD A8 vs AMD A10

So, I'm planning to get a laptop, I'm going to be using it for mainly video editing, and occasional gaming. I need to edit 720p HD video, and likely 1080i AVCHD video in Sony Vegas Pro, and the games that I will be playing are older games and indie games. Most will likely be PC exclusives since I already have an Xbox. Which processor line would be best for my needs?

- i3 Ivy Bridge
- i5 Sandy Bridge
- AMD-A8
- AMD-A10

I would like to get either the A8 or the i3 since they're the cheapest. Would they be enough for my needs, or should I try and get an A10 or i5? A discrete graphics card is outside my price range.

If you are looking at video editing with Sony Vegas Pro then none of the above. An i7 is really needed to do HD editing well and quickly and a discrete graphics card could be very helpful also. If as you cant afford it then the i5 is your best bet.
