    What is it really? Games obviously and 3D apps but what else?

    Seems like many people have the view that it'll benefit almost everything. Does it really? I have an old P4 PC with a 30 inch screen and a crappy GF 7600 GS. I've seen alot of slowness with the 6 year old workhorse but nothing that I could with certainty point out as being graphics card related. I'm looking for a mac pro for non professional Photoshop, Lightroom and HDV editing..... I guess they are the usual heavy 2D graphics apps that people use. Is there a real benefit from a 4870 compared to a GT 120?

    the 4870 is a beast, not the fastest card in the world, but it slaughters the 120 hands down, but they will both work fine but if you plan on playing games and doing heavy 3d rendering your either looking at 4 120's or the 4870

    thats my opinion tho

    Corrected that part for you :p

    Really no benefit in having four Geforce 120 graphic cards in the Mac Pro, other than being able to drive more monitors.

    Not so. Some applications use the GPUs much like OpenCL is planning on doing. Nvidia has been distributing code to developers to do just that - CES was showing off some developers running multiple GPUs to do video rendering that used to be handled by DSP cards.

    No pun intended but that is for Windows until we get Snow Leopard.

    OpenCL is, of course, going to change that. Still, the Radeon HD 4870 will be vastly faster than the Geforce 120, even if there were four of them.

    True...

    No argument there.

    I've never experienced Quad SLI but normal SLI is not worth it from my point of few, costs a lot for a tiny performance increase, which is lost as soon as you add more monitors, so the 4870 sounds like a smarter choice than the 120, unless you don't have the money for it
