you have to reboot macs in 32 bit mode - 64 bit mode is mostly just completely pointless - there isnt any performance advantage at all. its all hype. and bullshit -
5 years ago powerpc was all 64 bit -

ATI cards are currently broken - 5770/5870/4870 on 10.6.4/5 as of today 11nov2010 - nothing to do with 32/64 bit - drivers are broken in both.
gtx 285 is end of life - probably being replaced by gtx 580- but not much news on hacking sites

th2go issues are between matrox and apple - and drivers - what works and doesnt is completely up to them - and technical mini display port adaptor limitations.

apple did not port quicktime properly to 64bit - and they never will - so they said - who knows what they will junk or break along the way. quicktime X - their recent player was fundamentally an awful downgrade in functionality - someone forgot quicktime design paradigm at apple -

We have a new mac pro with a 5770 card. Many issues... First is it will only run 32 not 64 bit and even then the LFG input & Intentsity Pro cards can bring the os down when you enable it with various other random crashes, however once its running its solid. We have 2 THTG Dvi cards on the outputs and using the MDP - DVI adaptor the only resolution is 2400 / 600, whereas the dual link Dvi output works fine. However you can only use 2 out of 3 of the outputs at any time. I'm told that if we buy the Apple active MDP - DVI it will all work a treat giving 3 dual link DVI outs , but I'd be happy with 2.

Questions basically are...


Will apple fix the 5770 drivers anytime soon ? even then its going to need another adaptor if not 2 to work properly so is there any point waiting?


Does anyone any experience of the MDP Active DVI adaptor ?


Would the sensible move be to junk it for a GTX285 ?


Whats stopping Catalyst / Lfg whatever working in 64 bit and how likely is a fix for that?


Advice much apprecciated!
