I'd recommend not wasting money on just a SCSI controller, spend a little extra and get one that includes an accelerator if you can find one.
CV64/3D is an awesome card in a 2000! I had one in my 2000 when it was my everyday computer. I sold it when I got the CVPPC for my 3000. Now I need to find another CV64/3D because I am building the 2000 back up. No, I won't brag in this thread about the accelerator I bought :-D
