Real Mac Pro user here, stop whining, not knowing what you really mean:
I am not concerned about gaming on a Mac Pro. Get a PC or a console for this.
As long as I prefer to work on OSX and I have a PC too and I like a lot W7, but you know, I am an artist... "the weakest link in the IT department" -some may say, so what does he knows... The last time I payed $2,800 for a Mac Pro was in January 2009, But it was to purchase the 8 core from 2008 and replace my last Mac Pro 8 core from 2008, -Yes I sold in december the same model thinking Apple was introducing faster options in January. Estrange enough, at that time, the 8core Mac Pro was among the cheapest workstations from a recognized brand or any brand to include two quad Xeons 2.8 in the 2,800 price segment. It wasn't just me as I know many PC users who did the same I did and went for the bargain, and it was. Well friends (and I am among those who really can say this) I am not crazy enough today to DOWNGRADE my true 8core 2.8 to a 2.8 i7 quadcore and 4 treads. Yes, for single threaded apps the new Xeons are faster. But this is not why I in the first place I opted for the 8 core Workstation. RENDERING is why. And show me any benchmark in which this "NEW" 2010 Mac Pro for $2,800 is FASTER than my 2008 model RENDERING in 3D. APPLE, and INTEL too, get REAL. I wont replace my machine for these pricey underpowered machines. Actually, and thanks to the world for being rounded some options like real un-biased, physically based GPU rendering are available today. I will stick to my current Mac and PC and will invest my money on GPUs and on a OctaneRender license. An order of magnitude faster, still with limitations, but here today and available at a very reasonable price. Is not unusual these days to find great innovation coming from small studios.
2008 + Mac Pro 8 core Xeon = 2,800 2010 + Mac Pro 4 core + 4 treads = 2,500
Intel Xeon W3530 / 2.8 GHz - LGA1366 Socket - L3 8 MB = $321.89 to $373.20
No wonder Apple reduced the price from 2,800 to 2,500. So you "Save $300" and "a lot of performance too".
Bad Apple as there are way cheaper Xeon based machines. And bad Intel too, because today for double performance you need to pay more than double the Intel price, I mean double socket Xeon systems. It wasn't like that in 2008 from Intel and Apple. And it wasn't like this neither in 2006 and 2007.
AMD, come back to the top!
Well, the difference is I actually can say all this because I use and care for these products year after year, I spend my money wisely and is not just a biased or hateful opinion from one side about a specific brand.
Besides all this, desktops and workstations: Not the trend anymore. They will only get pricier on the next years and as a result slower and unreachable for single users. Big companies wont invest the same on these niche products. Get your superphones and tablet PCs. Ouch!!!
