Of course, you do have to watch out for colour rot on a CRT. I don't know the technical term for it, but every CRT I've ever owned has had the colours degrade in a non-linear fashion where the darker end of the curve gets progressively darker, ultimately getting to the point where it's impossible to differentiate between black and darker tones without severely blowing out the higher end of the curve.
For a while you don't even notice this, and I noticed that when I viewed my designs on a properly configured monitor I'd been overcompensating on darker tones across the whole spectrum. Lots of designs where I'd thought I'd put in subtle grey and such turned out to be... well, not so subtle.
CRTs are also significantly blurrier than LCDs, which I don't find desirable for fine graphics work although it's fine for photos and videos.
One saving grace for LCDs is that when they age, they simply dim —
very slowly. I personally prefer knowing that my colours and tones are at least displaying properly in relation to each other rather than having inky blacks. Not that I've tried the latest LCDs to see how they fare on the blacks front. My VIERA TV I got last year does excellent blacks, so it must be possible in thin displays nowadays.
With regards to hardware, most hardware bundles you get nowadays are more than adequate for web design. If you want to get a PC capable of handling all forms of multimedia work (video editing, etc), I'd go for something with a minimum of:
- Quad-core CPU clocked at 2.4GHz
- 4GB of DDR2 or DDR3 RAM
- Latest-series NVIDIA graphics card (~£50 is fine)
That shouldn't cost you very much nowadays, but runs the entire Adobe suite flawlessly.
Monitor-wise I'd go with a 24-inch 1920x1200 because it's just over the size of 1080p HD, which means if you do need to work on HD videos you can do so at their native size. Also it's generally a really nice size (any bigger would be too much IMO), that suits the way I work perfectly — I very rarely maximise windows, instead having them thrown all over my screen.
