    Default Is there any promise or rumor for new mac towers?

    also, how more powerful is the current family of towers vs. the earlier multi-cores, say ~2009.
    thanks,

    Not enough to spend a bunch of money on. We have both and they are pretty close to just as capable. Nice thing is, no complaints - both are power houses. Bad part, they are very close to similar capabilities - a little edge to CPU to the newer one. I'd drop an upgrade graphics card in your 2009, if haven't done so already. And wait for the 2013 release. Apple has to either shit or get off the pot on the MacPro, time is past running out. No new MacPro in 2013 ends the Pro market for them. They promised it though, so I can wait, even patiently. The current machines are pretty good.

    Takes graphics processing load off the CPU.

    Could you perhaps characterize that a little better for me cuz I bet graphics cards are expensive, but I'd make the jump if I could sense the improvement. I got 16GB of tower RAM so of course i hope I'm well set. Thanks

    Every last user leans on graphics processing differently than the next guy (or gal). Very hard to even generalize that you will benefit 'x' from adding so many times faster graphics GPU performance. Too many variables. You will benefit, by how much depends on what you use your computer for, how big the file sizes are, how hard the GPU works, how many simultaneous GPU processes you run and so on.

    The purpose of the graphics card is to take the code that is written to display whatever graphics you use, video, photos, games, etc, and crunch it out on the fly with conditions set by you, the OS,the application(s) that are running, and the data it is running on. Take something simple like a couple dozen open photo windows in a photo editor, every one of which is in ram, both on the computer and on the graphics card. Swapping from pic to pic and scrolling up and down large photos takes a lot of processing to display what you see, all maintained simultaneously to every window open on your desktop. With older slower cards, and less VRAM, more of that is done by the CPU instead of the GPU.

    Today's GPUs rival CPUs in processing power. In some machines the graphics cards actually assist the processing of the CPU when it gets hammered on. Not so common on Macs, but one example where it does is using late model nVidia cards, which support CUDA processing, which integrates the entire system to enable cross support back and forth GPU and CPU.

    I have no idea how to quantify a number for you. I don't sell graphics cards since the choices are so small on Macs that it is impossible to differentiate and create a market. So the only time I actually research which cards are capable of what is when I personally need one. Then I may spend days researching it, reading performance specs, studying how each small piece of the specification will effect the types of processes I personally do, narrowing down to that which would increase performance for ME.

    The hardest my machine ever works is in 3D gaming, so in the end I usually have to reduce the scope of my research to how well different high end cards will enhance something like Direct X or other game processing requirement. And every time I do the research the rules have changed enough that I have to learn what is important all over again.

    You will get a lot of variation in preference when talking over the best card for a task. But worth the discussion to see if you can improve your computer enough to make it run for another year or two. In my opinion, graphics capability is the first thing to show degradation in capability as a computer ages. I almost always order the upgraded card when I buy a Mac tower. And later in its life, replacing the card with a higher end one, will typically buy me more useful life. Costs have ranged from $150 to $600 typically, although once I bought a $1200 card as an upgrade. Today's higher performance nVidia cards run between $300 and $1200, so card price hasn't changed much over the years. The one I am currently running in my MacPro is the $450 AMD (ATI) 5870. It has yet to be less card than I need, and is a killer performer. The newest nVidia cards have it thoroughly beat in GPU performance. By how much, you'd have to do some reading on sites that compare them. Problem will be that almost no one in the Mac community does comparison on the Mac models competently. The good testing review sites are for PCs, like this. All the Mac cards have PC versions, so you can find them on the PC sites and draw your own conclusions. then research the Mac sites for bugs and shortcomings in that particular card.
