I feel like im spending a bit much on the graphics card considering my needs, but im not sure what a good step down would be.
I recommend at the minimum at least two hard drives. One for the main OS and programs, and then a second one for backup.
Or, what I used to do, is have a 500GB for the OS and applications, and a second 1TB drive for videos, music, photos, stored downloads, etc.
I currently have four hard drives. One 500GB for Windows 7 and applications, a 500GB for Mac OS X/apps/media, a 1TB backup drive to backup that Mac OS X drive, and a 1TB scratch disk for Final Cut (plus a small partition for a second Mac OS X installation, in case the first one fails for any reason).
Since I keep nothing of critical value on the Windows OS drive (as no one ever should), I have never lost anything of significance on this machine. Even if my main Mac OS X drive crashed, I have a complete backup.
I plan to get a fifth hard drive specifically for media and stored downloads. That way, even if I do a complete erase and reinstall of Mac OS X, all of my music, videos, photos, etc are completely intact and maintain their organizational scheme.
People underestimate the importance of backups, especially in these modern times. Think about it. If, right now, everything on your computer were instantly lost, what would you lose? Only copies of valuable photos of family and friends or from overseas trips? Only copies of thesis papers or college work? Only copies of work documents that would take endless hours to reproduce, if at all possible? Copies of music and movies for which you've lost the original CDs/DVDs?
The more I thought about it, the more I couldn't ignore backing everything up regularly and reliably. I'm also using Carbonite, the online service, to backup things like documents and photos. That way, if my home burns down and I lose all my hard drives, I still have valuable data on a remote server.
