First off why is the "LAN Card" too slow? I assume you are infact talking about the wireless LAN card, which infact uses the fastest 802.11 standard out their. It's far faster than the average internet connection, and would suit just about anyone.
Second, it's in pounds. Notice the british pound sign, not a euro sign, not a dollar sign.
As for the laptop, its a bit weak to handle modern games. Could get away with CS:S on it however. Pretty nice price for what you are getting, but need a bit more power to play games.
