I only have a laptop right now but... here goes,
Laptop Model: HP Pavilion dv7t
Processor: I7 2630 QM (OCed to 3.0Ghz on all cores)
Memory: 8gb of whatever HP puts in its laptops
GPU: ATI radeon HD 6770 1gb
HD 1tb 7200rpm main drive, 2tb Seagate Passport USB 3.0 External Drive
Optical: Again, whatever brand of Blu-Ray drive HP puts in its machines.
OS: Windows 7 HP Service pack 1
Speakers: I alternate between a Bose 123 5.1 surround system and a pair of Sennheiser HD 202 Headphones
Not the best machine, but it runs almost anything I throw at it at ~60 fps.
