I have no problem calculating maps with my 64-bit version of coot. I posted on the cootbb how I was able to compile coot on CentOS 5.2 since I couldn't get the autobuild script to work for me. Also I couldn't get the gtk2 version to compile (but it may now) so I compiled a gtk1 version. I was able to test the build with coot_test and the appropriate test files.
As for my two cents for crystallographic computing... 1) Linux flavor: We use CentOS since I administer the Linux boxes here and I was most familiar with RedHat. Sense CentOS is just free RedHat Enterprise it was an easy choice. I did try Debian but I found that I was spending more time learning how to do things that I already knew with RedHat. I've had almost no problems compiling or installing most software packages with CentOS 64-bit. 2) Graphics Cards: I like the Nvidia cards since they provide linux drivers. ATI also does now. I would say the only thing I don't like about them is when you do a kernel update you have to remake the driver. 3) Displays: We have dual displays on our graphics workstations, 1 CRT and 1 LCD. The CRT is for stereo and the LCD is for more workspace. I highly recommend the two monitor setup regardless if you are using stereo or not... it's nice to have space for all the windows that pop up. I had to give up my dual monitor setup on my desk for a 24" wide screen LCD and it's just not the same. 4) Processors: Our newest computer is a Core2 Duo and it's definitely fast. I would get the best multiple-core processor you can afford and maybe go a little slower to save money so it's not completely cutting edge. ==================================================== James M.

And I would give exactly the opposite advice, unless you are or have a guru who can devote time to fixing all the little things which still don't work under 64 bit OSs. (Does anyone else have any clues on why 64-bit compiled coot can't calculate a map? I need to look into it, but have a huge backlog of work at the moment.)
