The 540m should be able to handle WoW in high settings if you want a reference.
Thank you for the link and the product seems to be a good buy. But I'm concerned with the durability of Acer. I've heard quite a lot of not so good feedbacks regarding acer. What do you think about acer then?
I agree with you on the poor build quality skepticism. All I focused on were the hardware specs.
The HP dv6 WR2 mentioned is for you. From my experience, HP didn't disappoint me when it comes to durability.
The 5650 should be able to handle WoW in high settings as shown in this video. http://www.youtube.com/watch?v=YTpNAROcV4A
Note that the laptop in the video has better hardware specs. However, you should be getting only a few frames difference.
My old laptop is a compaq model which when I bought it was already turned over to HP. Its been quite good for these past 4 years. I was wishing to get something not too over expensive but with a midrange discrete gpu. I looked up your HP link but its already out of stock and deactivated.
