it's Mac Os X 10.6.8 on a mac Pro. I've read on this forum that 10.6.7 offers no advantages

I think you mean 10.7 - (10.6.7 would be a downgrade...)
Most new MacPros are being delivered with 10.8.2 - which is fine - but still possible to downgrade to 10.6.8 if required...

I'll upgrade to the latest Nvidia drivers. Things seem to have settled down (Catalyst made it through last night). The green lines problem was cured by forcibly installing the individual Nvidia drivers (the package installer said they weren't required).

Bit odd - never seen this problem - usually the drivers are a simple install?
Did you get a picture of the green lines?

Catalyst version is 4.40_m364_HD. Am I using the most appropriate version of Catalyst?

m364 is the current public release and necessary if using 10. or 10.8 - but also works with 10.6.8

yes, apologies, i did mean 10.7. is an upgrade to os x 10.8 recommended?

no, sorry. lots of horizontal green lines, about 1cm part. there were some flashes and dots too. once i got the drivers installed they disappeared. we've had an ATI Radeon HD 5770 and GT120 installed previously. i ran the cuda installer prior to running the downloaded installer

we seem to be running happily now, catalyst made it through the weekend. unless there's some performance gain or other advantages to be had by upgrading this is probably a good point to leave well alone, but i'd be happy to have your advice...

thanks again for your time and expertise!
