Here's the thing. I have a DV7-1245 Laptop. It runs games such as Call of duty 4 on low settings, at about 70 fps on average. But I really want to upgrade the graphics card on it. This laptop has an onboard video card , I know. But I've also heard that you can add a video card through the PCI-E port on the laptop? If so, which graphics card would work and how difficult would it be to replace it? THANKS!

Why are you complaining about 70FPS? 30FPS is generally the minimum that's considered acceptable. After a certain point (approx 72FPS), the human eye can't detect a difference anyway, so whether it's 72FPS or 172FPS, you'd never be able to tell. There is no way to upgrade the video on your laptop. If the graphics aren't acceptable, get a new laptop.
