how many windows can morphos do for composition/3d with a 32mb radeon 9250 vs a radeonhd 4650 1gb on my sam build amigaos 4.1 when your running a 1920x1200 screen?
Well, a using 1680x1050 resolution and have the 64 MB version, but one is for sure: it's enough windows to have a big mess on your screen...
I.e. theoretically the 64 MB are a limitation, but practically you'll only pretty rarely run into these situations. Nevertheless I agree, the 32Mb are a bit little though. But the 1.5 GHz Mac minis are cheap these days (several times seen them going for ~180 EUR). Also enhanced display is not that big benefit in everyday usage IMHO. I disabled it on several screens.
Anyway, get a Powermac G4 and you have a wider choice for gfx cards.
About the RAM: usually my 1 GB is used for about 20-35% goes up to 50% sometimes and close to never exceeds 60%.
Btw.: Can OS4 address 2 GB RAM and 1 GB VRAM (like in your said 4650)?
Anyway, I think genrally the Sams are rather nice little maschines, but IMHO the price/perfomance ratio is prohibitive.
