Graphics Performance is off the charts for that price range, check out the passmark scores for it. Win 7 rating 6.9, lowest subscore is of the HDD, mentioning this just for noobs.
And just look at the fan following supporting for it in the above link. They've modified BIOS and released stable drivers etc... for it too. Go for it eyes closed. And guess what that thing is so well built that it's staying cooler than most of the non-discrete graphics Laptops in the market.
I was also looking for something in a similar budget. All the options provided look great, but they don't come with windows. Need to buy a windows laptop for my dad for email, browsing and excel. I live in a different city so I wont be able to install windows for him. Can up the budget a bit for preinstalled windows.
