I have an OCZ Vertex 60gb as my system drive and cannot recommend this highly enough, it makes a huge difference to performance and considerably cheaper than Intel options. Intel do make the best SSDs but they are definatly more expensive in the UK, and OCZ come a very close second for performance / value for money. My only criticsm is they don't come with 3.5" mounting brackets, and you won't find many cases you can screw one into without mods, but sourced adaptor bracket in my local shop for £2 !
