Ok, so I've read a lot about modding the Mac Pro 1,1 but still have some questions... I have a Quad 2.66 GHz arriving this week or next I plan on a pair of X5365's if funds allow - otherwise the X5355 SLAEG's (I see pairs of X5355's for $150, but the X5365's are much more - around $500+ for the pair) Processor Q's: I see some listed as 'Matched Pair' Do the processors need to be 'matched' or benched as matches? Do they need to be successive serial numbers or something? I can see the potential importance of this, so I would like to clarify. Also, I am aware of the firmware update, so will find/do... RAM - after swapping processors, am I still going to run the 667? Also, what ram are people running. I see various providers listing RAM as 'for Mac Pro' I see apple 'qualified' heat-sinks being the massive ones, not like most standard sinks.... anyone running standard heat-sinks? wondering if it is an issue, if it revs up the fans, or what???? Sound will be a bit of a concern for this machine. VID - I see a lot of talk about the ATI 5770.... but I am seeing a couple different variations of the card - I mean physically. Like they are two completely different cards.... what's the difference? What are my best plug n play video card options? I intend to run my pair of 20" LCD's and my 46" LED Sony Bravia 1080P SSD - If I run 10.7 or 10.8, does the OS provide TRIM control? Or do I need a SSD with Native Trim? I have a 'Native Trim' SSD in my MacBook on 10.5.8 working flawlessly, but not sure how the MP hardware and the newer OS's handle this. OS 10.7 -vs- 10.8 I am really really not sure which way to go here. I have read a lot of discussion about running 10.8, and I plan to do more reading, cause as of now, it seems WAAAAAAAAAAY beyond me..... I haven't done any Mac hacking/moding and it makes me nervous since I don't know what I am doing. If anyone has a very concise, step by step thread, including links to files needed, that'd be great. The stuff I've been reading seems to cater to those who already know what they are doing to some level..... they lose me hahahaa My uses for this machine are as follows: Audio - Pro Tools HD10 with HD Native Card Graphics - Adobe Web Premium (Currently CS4, I'm sure I'll need to upgrade) Video - Final Cut - still need to buy, will get most recent version for OS picked I didn't know the 1,1 and 2,1 were dropped with ML Makes me wish I'da know before making the purchase a couple days ago... Is what it is.... So I'd like to figure out how to run 10.8 so it isn't obsoleted already. Anyway, any answers or directions would be greatly appreciated. Thanx ! ! !
