Lenovo IdeaPad V570A
Display 15.6'' (1366x768) LED
Processor Intel Core i5-2450M (2.5Ghz)
ram DDR3 4Gb
hard drive 750 Gb
nVidia GT540m, 2 Gb

I intend to use this for 3-4 years. The specs seem to balance in my opinion. But since I have the money and they are both close in prices I need to squeeze to squeeze the most out of my dollars. So any recommendations will surely help.
I'm not a die hard game fan. I just like to play footbal (PES/FIFA) but I like a lot to use emulators like N64 emulator (which worked well in my former computer) and also Dolphine (GameCube/Wii) emulator which was dead slow in my last pc.

Get the Lenovo Ideapad v570 and here's why:

the i5 chip and GT 540m GPU make a VERY strong coupling, they aren't great as a hardcore gamer pair, but for you an "occasional gamer", you cant go wrong with this choice, and Lenovo's are always solid machines

What about the 6gb ram and the usb 3.0 ports of the asus ?
