hey guys.. i need some help here in choosing one of these two laptops..mainly for gaming and watching movies..

first,
- Asus S550CB-CJ103H VivoBook 15.6"
- Intel® Core™ i7-3537U-2.0GHz
- 8GB DDR3 RAM, 1TB SATA HDD + 24GB SSD
- Nvidia® GeForce® GT740M
- Windows 8 64 bit

second is,
- Dell Inspiron 15R 5537-4500 15.6" Laptop/ Notebook
- Intel® Core™ i7-4500U-1.8GHz
- 8GB DDR3 RAM, 1TB SATA HDD
- AMD Radeon™ HD 8850M
- Windows 8 64-bit

for the dell laptop, would it be alright without integrated graphic to play some good graphic games?
is it an optional to choose whether it would have the touch screen or not? if it is, how much do i have to pay for that?

which of these has better audio performance? and what is the drawback of having non genuine windows 8?

i'm thinking of dell laptop because i could save some from it. but i still need opinion in this.

thanks, in advance

thanks nexus for your previous suggestion.

but i do have one last question. 3rd or 4th generation of intel, which one is better for gaming?

thanks again.
