- You can and SHOULD always look up information on the components different resellers list for products. Because resellers always have motive to make everything sound better than they are and sometimes they just borderline lie and live out "details" in their benefit. Intel has good site for their products: http://ark.intel.com/products/71459/
- MSI should be one of the "quality" manufacturers, although they are mostly known for motherboards at least around where I live.
- The most important factor in any laptop, especially gaming laptops for me is the warranty. Because they will be constantly used near their peak performance, these machines will overheat, they will get cluttered with dust and hair, they will likely have a vital component break after certain amount of years because of all of that. When your motherboard, processor or graphics card breaks beyond what you can repair yourself the machine is essentially worthless if you don't have a warranty because repairing it with all the shipping will take months and cost several hundred dollars minimum depending on the components and your location. In my country you can get a 3 year warranty at best when you buy from certain reseller, some manufacturers even offer warranty extensions beyond that.
I had a semi-gaming laptop (800 euros) break some 4 years ago ONE month after warranty had expired. GPU fried because of overheating, I diagnosed. It was a good brand (Asus) with 2 years warranty but what can you do when it's just expired. Asked around for estimates and they totalled some 550 euros including shipping, repairs and new components, data loss of course. For a machine that had no further warranty and was couple years old, I could have grabbed a new and better laptop with full warranty in a store for that price. But I actually decided to take a good break from gaming back then.
Seeing you already purchased something I can but wish you good luck with it
EDIT: Also note about AMD: Their processors have a history of heating more than Intel although they tend to pack more power for the price. After this lesson in thermal effects I'm considering my next processor value more carefully. I don't know if AMD has improved on the subject, it is quite possible they have but these things tend to haunt the average consumer for a long time which is why we have so strong AMD vs Intel and Nvidia vs Ati camps :)
