Got one dual 2.26. Very nice machine. As Owen says, get 6
2GB memory DIMMs and install 3 in each bank as pic shows ("Tom" in Swedish means "empty" 😉
. This seems to be the fastest combination. Read ArsTechnica's review for more info. (We ordered the machine at a local dealer who uses quality third-party memory chips, with warranty 'n all).
You don't need 12 GB for Archicad (yet) though. But it's very nice to have if you wanna run several instances of it, or Artlantis etc in parallell.
AC13 uses all 16 virtual cores for updating views, 3D and drawings, and is very fast. ArtlantisR2 also uses all 16 cores, and I guess Artl3 too.
Fast OpenGL is not needed for rendering, but may be for walkthroughs, which I don't do much. And since I've recently had a lot of issues with ATI cards I decided to stay with the basic Nvidia GT 120 (to drive one Eizo 2410W 1900x1200 screen) and upgrade later if necessary. It's been fine since. (Got the machine early May. I have no apps that rely on fast OpenGL.) No need to upgrade yet. Same goes for the standard 600GB hard drive.
The machine is also absolutely silent and stays cool.
