Clivey has a point, powerful laptops are the ultimate portable gaming system. It really depends on the user. If you travel a lot or work in a office you'll find the laptop suiting you better for entertainment.
On the other hand for most PC gamers who don't travel lots or when the only place to use a computer comfortably is at home because you can't find places outside where you can stay for a long time, you'd rather have a powerful desktop. Powerful desktops are for those who would like to experience the best visuals, but generally, a laptop can run everything, only some at lower settings. It's not that much of a loss.
It's not a bad idea at all to own a great laptop if you're willing to spend the cash.
When you say PC it doesn't necessarily have to be strictly running Windows. By the definition a Mac is a Personal Computer too, just running on a different OS. Maybe if it wasn't for the console people being so provocative I wouldn't use every opportunity to fight back. I did a review on my video card and there's always somebody bringing up that e-penis stuff when I only wanted to inform others about a great product. But on the other side the whole site would turn against me if I post any negative things about consoles and not even anything personal.
I never said I was dictating anything. I was only expressing how I felt and without breaking any rules. However, the guidelines do say that going way off-topic is not allowed. I'm only firing after being fired upon. I think the attempt to troll us PC users here is against the rules in the first place. And now you're using personal attacks as your opening. It's the console crowd that provoked me in the first place, led by a mod. And as I said earlier, I'll stop if they stop being provocative. Rocke did stop, but why did you have to fire it up again? If you don't feel convenient replying, you don't have to. Nobody's forcing you.
Notebooks can have SLI too. The best you can get now is the new Core 2 Duo T7800 2.6Ghz, whatever amount of DDR2 they can fit into laptops now, and 7950GTX SLI (8600M is slower). 7950GTX is only available for laptops. It'll be enough for Crysis DX9 definitely.
