tarangwydion: Sadly my ancient gaming laptop will be unable to run it. Well, one of these days I will get myself a brand new gaming laptop (except that I actually say that regularly every morning for the last several years already... *sigh* ).
I think gaming laptops are overrated. It's much more expensive than a desktop, for starters. My laptop has a whopping 16MB of video memory, though it's got half the ram of my desktop and more than half the processor speed, though it's a Pentium 4 M. I've been wanting to replace my laptop for the longest time, since the thing gets uncomfortably (painfully) hot and turns off from overheating in minutes, the battery doesn't hold a charge, and usb 1.1 is very slow.
I think I'd want to get some kind of netbook. I've had my eye on the Edubook for a few years, since it uses very little electricity and the batteries are expendable and far more future-proof ordinary AA NiMH, but sadly it's $215 (that's $150 + the outrageous shipping of Thailand). I don't use laptops for gaming much anymore, but I imagine it's at least sufficient for most pre-1995 games and emulators, and I'm not sure it's worth that price since I could probably pay $100 more and get something much more capable. $215 is still an attractive price, I think I'd get one today if they had a distributor who shipped to the US without a ridiculous $65 fee.
I've also had my eye on the Pandora, but that's far outside of my price range, though I'm getting a Samsung Epic in a few days and that should quell at least some of my interest in a laptop for a while. My current phone is about seven years old, so I'm getting a pretty nice deal for $150. Hopefully, it'll have been worth the wait. ;)
Anyway, my desktop has gone a long way since what it was when I got it as a hand-me-down back in 2004, it being manufactured by Compaq in 2001, but it's just about reached the limit of what it can do. I'd need a much better motherboard than I have right now, and after changing the motherboard once before, I'm not doing that again, I definitely want a better case.
My friend just got a new rig he's still paying off last month for $700. I don't keep up with this stuff anymore, it's too complicated for me, but I remember that it's got a hexcore which he says is supposed to be good. I can tell you, it runs Mass Effect 2 beautifully, and I'll probably be playing The Witcher 2 on that. His sister got a laptop last year for $1600, it does stuff my desktop couldn't do, but it's not worth that kind of money just to play on the go.
So yeah, I'd have to say go with a good desktop and just get a cheaper laptop. You could get an older laptop that's more powerful than a netbook for less money. Of course, the major caveat is that the batteries die, and it'd cost $60 to repair the battery of my Thinkpad, which simply isn't worth the bother. Hopefully I can get a desktop around $400 sometime that can play stuff like The Witcher 2, but I really don't understand any of this stuff anymore, I've tried shopping around and looking at Newegg but it's confusing. :P
