How Well Will I Be Able To Run PS?

[Wolfen]

Well, the title says it all, really.

Specs:

Geforce 2 MX/MX400 (probably gonna upgrade to a PNY G4 ti4200)
Intel Pentium 4 1.7GHz
512mb RAM (not sure if it's DDR or whatever, my system properties just says RAM)
I'm not really sure of my Mobo's name and make, how would I check that?

I've been looking into overclocking my processor and vid card, but i'm not sure how I would
go about doing this. Any links/tips would be most appreciated.

Thanks
