Thanks for the input, I will definately get the 120 SSD, and have a look at steam to back up my games to the 160 HDD. Great advice.
I should explain that my first computer was a 486 DX 266 running windows 3.11 and DOS 6.22 with a 420 Mb HDD, I bought a 500 Mb HDD to go with the 420, I remember installing DOOM and Wolfenstien 3D on my D drive once to see if I could still play the games and for some reason it didn't work, so I have never installed anything on my D drive since, so I have never tried to swap games or run programes from my D drive.
The best thing about that was everytime I formatted my computer, I had to start the game from scratch so games would last me years :). I am a bit fussy when it comes to the perfect clean install , even if an error came up on say my GFX card, I would format again, sometimes 4 times in a day. Then again with win 3.11 and a 420 HDD it only took about 1 hour to install everything.
