You made some valid point.It was manufactured this February. It is an i7 processor, 8gb of RAM and a solid state drive (which absolutely flies). I tried playing Diablo 3 on it and it was pretty choppy. It does have some mobile nVidia card in it, but it is low end. I could probably play like Counter Strike on it and those kinds of games. Of course this is specifically to be a work machine. Unless you're playing games or doing high end graphics work, they skimp on the card. I put the specs together and went max on everything available. This is a Dell. They may have different model lines that have more graphics power too.
Its true, that in order to play AA games well, you need a PC/laptop specifically for gaming, with a gaming focus GPU. Yes, its true, there are people out there that still think that having a current off the shelf PC/laptop, means it can run games well.
The plus point for a gaming PC is that, if it can run games well, chances are, it will run your work applications well.
Yes, it still requires a bit of technical knowledge to be a PC gamers, & picking the right readily built PC or build your own can be quite tricky. But think about it, desprite these hurdles, PC gaming is still on the rise! I would imagine it will attract more mainstream PC manufacturers to make more gaming PCs, & I see premade gaming PC price dropping to similar, if not better than DIY PCs soon due to economy of scale.
