Not all quad cores are created equal. You should try for a newer Intel i7 model.
Also 8GB of memory is probably a good minimum. More is always better.
And with the new ray-tracing feature in CS6, you'll want a 500 series nVidia graphics card as well.
Those are some good starting points. Once you find something with all that, post back more details and you'll get more opinions.
I'm quite interested in the subscription setup too.
I have an early i7 Xeon quad core in my machine. ( W3820 2.6Ghz thing - Dell T3500 ) and a GTX260 graphics card, 6Gb RAM. A few years old now I suppose.
Its handled the trails of CS5.5 without too much fuss in terms of being able to scrub through AVCHD files, and apply simple effects in Pr . After effects ran fine as well for me and I was able to mess around with particular effects quite happily.
I know my machine is far from all the SSD scratch drive, multi drive arrays, mega graphics cards .... but it does handle AVCHD stuff well enough for me. I plan on a upping the RAM and HDD space, but in terms of my workflows, it suffices.
Thanks Jim. At this point I don't want to invest in a i7 model. My needs are ultra simple. We intergrate some video training clips with Camtasia sceeen captures and an occasion green screen. I have to render my green screens now at full res so not worried about rendering final images to see.
I am more concerned with just working and not having any tech issue. I haven't used AE in 10 years so I am not up to speed with the current software.
I can get an i3 quad at an affordable price and as long as the software runs reasonable well I am fine with that.
Just want to make sure it will function. Will definitly load up on RAM.
