Ah right. I didn't pick that up since the article didn't mention the Mac Pro and there's no GPU for that model with 1GB of VRAM, not one that I know of anyway.

Seriously how have they not fixed that? It impedes even basic performance and its honestly an embarrasment. How can they let such a major performance hindrance go unfixed?

The 5770 is very popular upgrade for 06 and 07 MP because it still supports 32bit EFI. Even with the 5770 MP 1,1 and 2,1 are not supported because of the 32bit EFI

Well, ML is supposed to address that. Which does me no good if I can't update.

thats true. but ive also read that apple is switching to all ssd partly in order to improve performance. maybe they think they can just throw more hardware at the problem

I haven't had the luxury of running OSX with an SSD yet or having massive amounts of RAM (currently using 4gb). I hear OSX runs so much better with SSD and massive amounts of RAM though which is no surprise as the OS is very resource hungry.

i really hope that is not there solution. im planning on getting a rmbp and if it really runs that slow, i will just uninstall osx and put linux on. im buying it for the screen and battery mainly anyway. running a web browser should not take 2mb of ram, obviously there is a memory leak somewhere.

even if it runs well with ssd and more ram, it is damaging to the hardware to be so heavily taxed constantly, even for light usage. i guess apple is a better hardware than software company.

What's this about memory management problem you mentioned?

The rMBP won't run slow. Macs are quite fast... OS X just gobbles up RAM like a hoard of children devouring candy... it loves to cache everything. It caches your caches just to be sure... Photo Booth needs to be able to re-open in a nano second. lol.

And no using up lots of RAM doesn't damage the hardware. (Correct me if I've missed the point here, but it sounds like we're talking about RAM usage.)

I believe the issue is that OSX (SL and Lion) holds on to your inactive RAM for longer than it needs to making it unavailable when you actually need it so it starts to cache onto your HD. I have a 5200RPM HD so yea, you know how that goes. At this point, I'd have to go into the terminal and manually purge the RAM to free up the inactive memory or do a restart. I doubt you would notice it (at least as bad as I do) on the rMBP with 8-16gb of RAM buffer plus an SSD to cache on if it needs to.

But I believe they fixed it in ML since some of the people using the beta have been commenting on how much more readily the RAM is available.

i just meant in general having a computer at high load all the time can be bad for the hardware (especially for laptops with their relatively poor cooling)

thats good to hear, i hope thats the case. i do prefer the file system of osx, it just seems more logical than windows to me (more linux like) and the boot times are way better. and it can run netflix which is a huge plus over linux as far as im concerned
