I did ask in the steam thread, but didn't get a reply. Anyway does anyone know if my pc will be ok for running Saints Row 3?

Windows XP (yeah I know "get with the times" etc etc)
Intel Core i5 2500K @ 3.30GHz
4.00 GB Dual-Channel DDR3 @ 665MHz
MSI P67A-GD53
512MB ATI Radeon HD 5670 (1024x768 res)

I miss the days when companies put out demo's lol
