Yeah I know everyone has different experiences or approaches, I get it. For me though, unless a new GPU, I just update on top of old. Never had an issue. One the other hand I don't use multi-card setups or extravagant tweaks or OC's so in the end for me it doesn't matter.
I don't know Mike; honestly, I've been doing updates to existing drivers going back to my ATI 8500LE days back in 02. Rarely have I had an issue. And I've been with AMD (ATI) since NVidia bought out 3dfx.
That said, I would never advise anyone NOT to do a clean driver install, I just never experienced an issue not doing it myself.
