The interface on hat laptop is USB 2.0. Topping out at 480 megabits per second you PCI 1.0 slot (that's very dated) is moving about 1,067 megabits per second and I'm not showing what PCIe does yet.
This is the easy reason why you can't put a video card on USB 2.0 and play games.
You'll find the Xbox/PS3 to be the cheap fix.
I've tried to do some random searches on Yahoo and Google to get the answer for this, but a lot of the posts are dated from a couple years ago, and not knowing a whole lot about this sort of thing I figured I'd find a forum to possibly help me out.
I have an HP G71-343US laptop with a Mobile Intel(R) 4 Series Express Chipset Family graphics card (or at least I think that's my card). Anyway, what I figured out on my own is that the drawback to laptops is that they're not very upgradeable and playing videogames on them is best left to desktops. That being said, I came across the option of external graphics cards. Some of the older posts I came across said things along the lines of them not being compatible or only giving minimal performance upgrades.
So my question is, are there external graphics cards available today that might be helpful in helping make my videogame experience faster and smoother, or am I still in a jam because I own a laptop?
