Are my specs good enough to play Soma?

[Firia]

I haven't had an opportunity to upgrade my PC in some time. It's just not in the finances, cheap as some options may be. But I still find my set up isn't toooooo outdated to play some games. But... I don't really have a basis for understanding some minimum requirements. Like Soma's. Can anyone tell me if the below specs are enough to play? (Some of these I know are enough, but I'm just including ALL my specs so there's no guessing.)

OS: Win7
Proc: Intel Core 2 Quad Q6600
Memory: 4gigs
Graphics Card: Nvidia GeForce 8800GT
HD: 150gigs free

Mostly the specs I'm unclear on are the Proc, and the Card.
