I hate all used dealers which claim to support Apple Mac products. Every single one of them are rip-offs - no exceptions. They are dishonest in the part selection. Like they'll add heat sinks to server RAM, call it "Apple Approved" and charge almost double for it. Or they'll sell you used RAM and call it new - of course charging new prices. If there's any real trouble you will have to pay the shipping IF they'll even accept the return at all. Mostly I hate them just because their prices are between 150% and 250% of the going rate with no actual added value. They also hide information about the machines they sell. Look around and see if you can find even one "Mac" shop selling RAM for example (installed or individual) where they tell you who the manufacturer of that RAM is. Mac used shops are dirty and underhanded IMO - though I suppose it could be just ignorance and laziness. <shrug> Either way I personally stay far away from them!
I like the pro idea a great deal. It also addresses a music challenge I have as I could use a drive to store my music until I get around to building a NAS.
I get the idea around SSD and the two seagates. Is the "flavor" of memory important in your view? IBM server vs going to OWC, for example?
Finally, I know nothing about video cards. I see the nvdia on eBay, but is this replacing an existing one or being added? Is there configuration required or does it all just work? Could the video piece be an add...Show more →
Nope, not important at all. I do like brand memory though. I always buy used Kingston or Crucial - which show up on ebay from old datacenter tear-downs. You need fully buffered but that's about the only spec you need to focus on. They need to be dual column but I think just about all FB-DIMMs are until you hit the 8GB modules. You can even use the 667Mhz modules suggested for the earlier MP1,1 and 1,2 models with no humanly detectable slowdown. You can also use NON-ECC RAM but you can't mix it with ECC. I don't recommend it tho - ECC is good to have. So just get used server DDR2 ECC FB-DIMM either PC-5300 667MHz or PC-6400 800MHz whichever is cheaper. You do not need "Apple approved" RAM with those ridiculously large heat sinks. Those were needed for the very early 256MB, 512MB and some of the early 1GB modules but later larger models don't need it at all. I suggest buying all 4GB modules and selling off anything that isn't. You can place 2, 4, 6, or 8 of them in - and of course you can buy them over time two at a time. Two of them is 8GB and that's actually enough to get by on. OS X 10.7 and I assume 10.8 grinds at the drives (even with no applications loaded) with anything less than 24GB installed - but between 16 and 24GB it's fairly slight.
If you go for less here's a console command which will eliminate all of the grinding (thereby speeding up the machine by about 7 to 10% - seemingly) regardless how much RAM you have installed - until you get more:
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist
followed by a reboot. You can turn it on again with
sudo launchctl load -wF /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist
Yes, the video card can wait if you like. The only extra goodies you'll need are power cables as the MP main board uses a different size connector. They're about $5ea and you need two of them (I have an extra 40 of them if you need). If you install 10.7.x Lion or higher in your system the card will just drop in and work. It's a replacement but keep the old card handy (in a closet or something) in case you run into trouble and need to see the boot screen for some reason. Ya see, when you place a BIOS type card in a MacPro you don't get to see the boot screen that shows up when you hold down Option while booting. It's a minor inconvenience (I never notice it at all) and there's a utility somewhere that works around this limitation - but I've never needed to install it so I dunno what it's like. Once booted everything works just as if it were an EFI Apple GPU card. You'll get OpenCL and OpenGL, as well as CUDA in all applications which support it. Any brand card will work but I would recommend getting one with 2 or 3 fans - or something that is otherwise known to be silent - for the obvious reasons.
The MP3,1 will probably come with either an 8800GT or a 1900 ATI. Some may be upgraded to something like a GT120 but you probably won't find a MP3,1 for cheap that has a CUDA/OpenCL capable card in it. For music editing, light still photography, internet surfing and the alike you won't notice any difference between one of those and the GTX-570. But for video editing, heavier still processing, and games (there are some cool games on mac these days) as well as 3D rendering and so on the 570 will be a noticeable improvement. The feeling between the two isn't GREAT but the GTX 570 will almost never lag and your times will improve by something like 10 ~ 15%.
Here's some screen shots of a GTX 570 that I dropped into a MP2,1 running 10.7.5. I didn't do anything other than plug in the card and connect the two power cables to the MP main-board.
