So I've been going back-and-forth between this question - Should I build a gaming PC or buy a Laptop?  Until now, I really haven't been able to decide, but I think I've decided on a laptop with the rationale that:   

1. The only PC exclusives I want are Starcraft II and Civ V, and anything else I'm interested in will probably run on the laptop I'll get or be on the 360, which I have.  
2. I won't have to be secluded in my room on a desktop, as I can be on the laptop anywhere. 
3. I will save loads of space because I won't need to buy a keyboard, monitor, etc.  

• Acer Aspire AS7741G - 17.3" Intel Core i5 460m (2.53GHZ) 4GB DDR3, Ati Radeon HD 5650, 500GB 5400rpm HDD
• Same as above except with Phenom II Triple Core (2.2GHz)
• Same as above except with Phenom II Quad Core (2.1GHz)

1. Which processor would be best for gaming? I've read that Quad-Cores currently aren't being utilized by most games but will eventually be. I know nothing about Intels.
2. Would I be able to play the games on my PC Wish List? (See below)
3. Is there a better laptop in the price range I should be looking at?
