@SDBusDriver1979 That's because Modern Warfare 2 on the PC is pretty much a straight port from the Xbox 360. If you dig around in the code, you can find things like 360-specific commands and 360 error messages.
Valve should devote more resources to developing the Steam web browser (which is basically Internet Explorer at the moment). They said they're looking at alternative web browsers to embed such as Firefox.
I've been using Win7 for a little over a week now and I like it a lot better than Vista. I LOVE the UI improvements. The increased performance is very nice as well. There's pretty much zero lag after quitting out of a game. In Vista, things would be chuggy for maybe around three seconds or so after quitting a game.
The GTX 260 or HD 4870 are what you want. If you buy on Newegg with Paypal, you get 15% off, and you can stack that with Live Cashback for some good savings.
