Criteria new computer

Hi, technology changes rapidly, and after a few years everyone has to make a choice about new hardware. Now it is my turn...

I could not find many guidance via Google besides some very specific questions and answers on ASKBOT, Sage-support or Sage-devel. Most related are and (

What are reasonable standards today? What is nice, but not overdone? What is student level, semi-serious, and top-of-the-bill? What are criteria to buy now, or to wait for say 3-6-9 months? Is the Windows experience tool handy? Many related questions.

Based on the above suggestions: 1) Sage is single core: duo core or 4 core seems also good, isn't it? 2) 16G. Does Windows 7 + VMWARE (32bit) or Ubuntu (64bit) need it? 3) SSD is still. But does it increase speed? Value for money? 4) Are there different requirements for integer MIPS, floating point MIPS, specific applications? 5) Any other considerations, as internet speed?

The same questions, but asked differently. What is nice, but not overdone, for: a) Some integer, floating point or symbolic computations (calculation up to 15 minutes, memory usage < 30Mb)? b) Same as a), but calculations of 8 hours (mainly Cython) and a lot to save?

A third approach is budget related. If your budget is $300,400,500,750,1000,... What are the main issues to consider? (N.B.: Europe is more expensive). Is it just mainly Sage or it is a multipurpose machine. Last: simple PC will do, and heavy stuff possible via sagenb / KAIST (and maybe cloud)? Or should I wait for (multi-core) Cygwin?

Many different questions, but some guidance would be appreciated. For me heavy tasks as gaming, video , photo and music are not relevant. Up till now it seems that Intel Core i7-200k 3,4Gzh 8Mb, 16 G memory with 120SSD+60SSD will do. I can use two OS. But makes it sense? Thanks in advance for your support!

(It may be an idea to have a sage page for it, because it seems to me that it is a general question relevant over time for many).
