I owned two Picasso II's before trading up to my Spectrum. They're not bad cards, really, but I could never get the input on the switcher to play nice with the output from my Indivision ECS (I wanted to use only a single monitor for all screenmodes - the PII is not a scandoubler - if you feed it 15KHz input, it will output 15KHz, unlike the more advanced PIV cards). I tried two different versions of PII and even had some correspondence with Jens, but eventually gave up and got the Spectrum card, instead.
You want to use the latest Picasso96 software with it, which I think you already have a link to download, and if I recall correctly you've already learned how to set different screenmodes. For me the best balance of performance vs quality was around 800x600x16-bit or 1024x768x8-bit, but of course your expectations may vary and you may choose to set up a screenmode that's completely different, with a monitor that's completely different, lol.
BTW - don't use segmented memory mode on the things. Yes, you can. But no, you shouldn't.
