Converting between displayport and dvi

[[TW]Fox]

Hi chaps,

I have a PC, a PS3 and an Xbox 360.

For the Xbox 360 I have a VGA cable. For the PS3 I have a HDMI to DVI cable. For the PC, I have a DVI cable. My graphics card is dual DVI out and has no Displayport.

If I was to buy a Dell U2312HM, how could I connect all three of these devices conveniently?

Can I easily convert the DVI output of my PC to Displayport? What about converting the DVI end of the PS3 cable to Displayport?

What about a DVI switching box. These seem to be available from just £10 upwards and accept 2 DVI inputs and output one DVI output. You then press a switch to swap between them. This would work - are they any good? They range from £10 to over £100!

99% of the time it'll be with the PC. I don't use the PS3 a huge amount.
