new install of windows 7, should I partition my HD?

[turbotalon1g]

ok originally this laptop had windows vista and a 250gb HD that was partitioned into 70gb for the C: drive and the rest for the E: drive.

I wiped the laptop 100% clean of everything even OS and now with the fresh windows 7 install it just has a single drive of 232GB, Should I partition this and keep the C: drive clean and use the other part to keep all my music,movies, downloads, etc.?

Thanks
