Which computer is better?

I am not trying to build a computer. The desktop has already been built and has been around for about 2 years. My friend got a laptop in the summer of 2013 and I want to know who's is better in terms of raw performance in games and everything.

I know I am comparing these two like apples and oranges, but I am just curious of which one is better.

DESKTOP:

FX-6300 OC @ 4.75GHz

GTX 550 Ti OC 20% more

8GB 1600MHz RAM

WD Caviar Black 1TB 7200RPM

Crucial M4 128GB SSD (Boot drive)

3x 2.5" 5400RPM 250GB laptop drives in RAID 0.

LAPTOP:

Intel i7 3630QM 2.4GHz

GT 650m SLI

1TB Generic Seagate 5400RPM HDD

8GB 1600MHz RAM

Those were all the specs of the Laptop that were listed.

Thanks
