Radeon is the best if tou dont care about 3D. If you can find a VooDoo 3 its very fast and well supported as well as having full warp3D support.
The ram isnt to bad as well. I have 650MB in my A4000T and love the extra room to run what I want.
Since he is using a 030/40 i am willing to bet 3d won't be of much use

I have about 500MB of ram on my A4000 and i use it like crazy, i do everything in ram it seems

I think it was amigakit who posted the pic with multiple zorams at 1GB.. in theory zorro3 space is 4GB,so even that 1GB could be exceeded if you have the slots.
