Mac desktops: New Mac Pro: Buy Now or Wait?

Mac Pro Buy now or Wait

I have two Mac Pro units, one the top of the line 8 core and the other the bottom of the 8 core series. They are exemplary in every respect. They are essentially silent, have no gliches and for a change, they sleep and wake up unlike many a machine heretofore. The fastest unit does discharge some heat but it is not obtrusive though I would not place anything behind it as it is warm..not hot. Nonetheless it makes no noticeable noise unless one listen closely to it. The lower end is as if it were not on..cool and silent. In terms of functionality, I suggest getting at a minimum 4 gigs of RAM but from a third party for the additional RAM since Apple charges hugely for the privilege of installing it...which is a no brainer. Installing Hard Drives is a five minute job and removing them...ten seconds as one puts drives onto a carrier that locks in and unlocks just like click...done. It is elegantly clean inside and lots of room for cards. I have an eSATA card for an example. I suggest that you go for the middle cost graphics card but not the top of the line unless you do 3D design work. I do not. The machines are unlikely to be upgraded for a while until Intel supplies 35 u chipsets in 8 or more chore configurations. Frankly, the machines are so damn fast now that I do not see the necessity for an upgrade unless the software changes radically in this regard. Write to disk on the internal disks is extremely speedy and number crunching is just a second or so for most activities and even the Finder is a lot faster than anything I previously used. The G5 is MUCH slower, noisier, energy consuming and in my case the worst machine I ever owned to the point that Apple replaced it with the bottom end Mac Pro which is why I have that one when they were unable to repair it at all. I would suggest getting rid of it before it dies and you cannot unload it to be frank. It is a dog but the Pro is anything but. Go for it...
