Hi, I'm looking to buy a new laptop, and I want to be able to play Sims 3 well on it (my current laptop does run it, but verrrry poorly). I've narrowed my selection down to three, and I'd like a second opinion. Mobility is also an issue; I'd rather a 13.3" screen and the lighter the better.

In price order, highest to lowest:

1) Samsung R522-JSOPL.
Intel Pentium Dual Core
2.1GHz
3GB RAM
320GB Hard Drive
ATI Radeon 4330 512MB
Windows 7 Home Prem 32 bit

2) HP Pavilion dv6-2100 - or HP Pavilion dv6-1400. I'm not exactly sure of the difference between these two (apart from price!). This is the link I'm looking at: http://h10010.www1.hp.com/wwpc/uk/en/ho/WF04a/321957-321957-3329744-6435...
Having just seen it in real life, it seems quite heavy and bulky. Is there a 13.3" version?

3) Acer Aspire 5732ZG-433G3Mn
Intel Dual Core T4300
2.1 GHz
3GB RAM
320GB Hard drive
Radeon HD 4570 512MB
Windows 7 home prem 64bit

The Acer is my favourite looking and feeling one, but it doesn't have bluetooth, which is a pain. It's the cheapest though, so I could always get a usb bluetooth thing.

I would really appreciate some help - I really want to make sure I'm spending my hard-earned cash wisely! Thanks a lot in advance.
