What are some good video card upgrades for the Acer Aspire one 11.6 inch version?

Netbooks, such as the one you have, are not a good choice for a gaming rig. The CPU isn't as powerful, and with most laptops, the video card is integrated, meaning you cannot swap it out. If you are serious about gaming, you're either going to have to buy a decent laptop, or else build a desktop machine. If you're concerned about upgrading, the desktop would be your best option.
