I actually find PC Specialist to be quite good on the gaming laptop front. The downside is you kinda need a little PC knowledge, or you need to call them, since you can pick your own parts to customize the laptop. I always recommend them over Alienware to people... same with Scan as they're doing their own brand, decent gaming laptops these days (which shocked me!).
Flynn, you'd be surprised!
I've seen good benchmarks from Xeon CPU's. Not as good as a Core i7 Extreme (and to be fair, if you can buy a Xeon, you can get one of those beauties), but very, very close. I've always said, if I win the lottery, I'm building a twin Xeon computer for rendering and gaming.
Wolfy, that will probably do the job. The CPU is ok, the RAM is more than sufficient and the graphics card is a mid-range dedicated one. It should, in theory, be faster than my laptop, and I can run The Sims 3 with all expansions with no problems. There is a little slow down after several hours, so I have to reboot, but that computer has a slightly better CPU, a better graphics card and more RAM.
