A1200 RTG options

It should be pointed out that if you run through a TV card, the quality will be normally a bit worse, and there will always be a few frames of latency.
Your best bet is a monitor with composite video in, or even SCART in for RGB.

It seems that there is no big difference between Zorro 2 and 3. Everything plays same speed with same RTG card and CPU, no matter is it Zorro 2 or 3.

That depends entirely on what you're doing with it, though.  No way I'd use a Zorro II card on my 4000 if I could possibly help it, far too slow. Heck, Z-III is too slow really these days, and Z-II is a lot slower than that.

The Picasso II is a Z-II card, so wouldn't benefit at all from being on a Z-III bus.
The Pic IV is much faster than a Pic II, and would I imagine be noticeably faster even on a Zorro II bus.

A Pic IV will be a lot faster in a 4000, especially where there's much data flying around - the chipset is several years newer and the bandwidth is much higher on Z-III. Putting it on a Z-II bus will just starve the Cirrus Logic chip of data for most of the time.

Still better than AGA for most things, though, of course.

I always thought the Picasso IV was Zorro III only.

Nope, it even came with a little snap-out board to fit into the A2000's video slot (which isn't in-line like the Z-III machines).
