Buying alienware Laptop, is it worth the money..?

I want to buy the alienware M15x, I want to configure it so it has a 1GB ATI Radeon™ Mobility HD 5730 and a Slot-Loading Dual Layer Blu-ray Reader (BR-ROM, DVD+-RW, CD-RW) which will make the Lappy $1399.

Full specs:
intel® Core™ i3-330M 2.13GHz (3M cache)
Genuine Windows® 7 Home Premium, 64bit, English
15.6-inch WideHD+ 1600x900 (900p) WLED
3GB DDR3 at 1066MHz
250GB SATAII 7,200RPM
Slot-Load Dual Layer DVD Burner (DVD+-RW, CD-RW)
1GB ATI Radeon™ Mobility HD 5730
Primary - 6-cell (56Watt) Lithium-Ion Battery


Would it be able to play StarCraft II when it comes out? Diablo 3? Sims 3? World of WarCraft? All of these games at high settings?

I love video games, but I don't play high demanding ons such as crysis or other games like it, pretty much the posted games above are what I play.

Is it worth the price? and will it last me for many years graphics card wise? CAN THE VIDEO CARD BE REPLACED IF I WANT TO UPGRADE? IF SO HOW MUCH?!?

Thanks and sorry for all the questions.

I have seen mixed reviews about Alienware. It seems that you pay a premium price. Performance is meant to be up there with some of the best.

To me it seems like it's worth it, but I keep reading reviews that they're either Good or Horrible.

People say they have lots of software and driver issues.

I'd buy one; just make sure you get a warranty.
