The reviews say it has a cheap ass fan.There is another one that is only 10 dollars over 800http://www.newegg.com/Product/Product.aspx?Item=N82E16883229253however i dont know how reliable GeForce is. Its Memory is twice that of the first one i saw.
GeForce is Nvidia's main brand of consumer GPU's.The only other brands are for workstations (non gaming use) and stuff.
So the second one is better?
Not really.Whilst the 6870 is near equal to the GTX560, AMD video cards tend to work better with AMD CPUs, so the first one would mean marginally better performance.Also, if you really want and need a laptop, I suggest this:http://www.newegg.com/Product/Product.aspx?Item=N82E16834246153

If you're looking for a laptop, consider this:http://asia.cnet.com/product/samsung-r580-core-i5-520m-processor-24ghz-4gb-ram-45180795.htmThis is the computer I have, an Intel i5 Processor with 4GB of RAM can handle Minecraft, Gmod and Blockland very well.It also has a very sleek design and comes with a webcam and mic installed. The only complaint I have about it is that it's a fingerprint and dust magnet.If it's not fast enough for you, you could always upgrade the parts.
