Eh, what are your computer specs? Download
CPU-Z (Download link is on top left of page), let it detect your specs. If your CPU is running 2 GHz or above, if you have 512 MB or more of RAM, and a decent graphics card, definitely install SCP. Links are in my siggy, as well as Turey's. If your specs are below the above, you probably can still install SCP. Post the specs here as an attachment (hit "Additional Options..." below the reply box on the left; if the link is not there, then press the "Preview" button first).
PS, if you have dial-up or a slow connection, let me know... hip63 got me a DVD that I can send you.
