My price range is $600-$750. I plan to use the laptop to play games such as Saints Row 4, Minecraft FTB (130+ mods installed), TES 5: Skyrim, and Assassins Creed 4. I would really like to know which is better for playing these smoothly. If you have a better suggestion for a laptop within the price range, please don't forget to mention it. Thank you all ^w^

Added (1). The current laptop that I use is an Acer Aspire 5251-1805.
It has a Single-core AMD v120 (2.2GHz) processor, 3GB of Ram, and an ATI Mobility Radeon HD 4250 Graphics card. It runs Skyrim (on lowest settings) at about 5-20 fps

First, if you want a good gaming operating system do not go with Windows 8 you will be disappointed. Second, you will want one with a better processor because I have a processor on a laptop clocked at 2.6 ghz and it could even run saints row 4 without total system lag and it crashed my computer 4 times. Both of those computers would explode if you tried to run Skyrim on them. Last, if you want an even better computer save up and build your own computer. There are a lot of advantages with building your own. I built my own for about $800 and it runs everything perfectly.

Both of them unfortunately don't even have a dedicated graphics card, only Intel HD 4000 graphics. For your budget however you can get one with a decent dedicated graphics card, like a GeForce GT 755M from Lenovo for $719. Http://shop.lenovo.com/us/en/laptops/ideapad/y-series/y410p/

What sets gaming laptops apart from regular higher end laptops is the graphics card. That's going to be the bottleneck when it comes to your gaming performance. Most current generation i5 or i7 processors can handle the CPU side of the games but not the graphical side without a dedicated graphics card.

If you're not that good with comparing tech specs, a good practice to get a rough idea of how well a laptop is going to perform in games is to simply type of the graphics card name into YouTube. Ex. "GT 755M"
