There are new processors coming out literally every week. x86 processors, which most desktops use, are also coming out almost very month.

The latest release that I am aware of was the new higher-efficiency AMD Phenom II cores, but Intel, VIA, Transmeta, and AMD are all working to put out new CPUs all the time.

There are also non-x86 processors such as those in phones, videogam consols, embedded computing, laptops, and mobile devices like iPods and PDAs coming out all the time from manufacturers suchs Motorola, Samsung, Sony, IBM, and VIA just to name few.

And then there's hundreds in videocards (nVidia, ATI, AMD, Intel, VIA, Matrox, 3dLabs, Volaris, etc.), peripheral components (Realtek, VIA, Samsung, OCZ, Kingston, Creative, etc.)

You will either need a "dual-head" video card, or two video cards. Check that the medical monitor conforms to a PC standard - it may not. If it has a HD-15 or DVI video connector, then it should be standard - and easy to find a card that will work with it. If it has 3,4, or 5 BNC cables for video it will be much harder. In that case you need to look for a workstation graphics card - and probably something that is obsolete now. (Cheer up - that means it's cheaper!)

To use the full capabilities of this "high resolution" monitor, you may need to use a workstation graphics card even if the monitor has a standard connector. Check the refresh rate and resolution, and then compare with high-end consumer cards, and with workstation cards.

Some cards will support a very high refresh rate, but only at low resolution.

By "workstation card" I mean something like an nVidia Quadro or 3DLabs Wildcat or ATI FireGL. Note that these can cost upwards of $3000.
