[EnergyPlus_Support] Model too big and too complicated? Part 1 - PC Performances

Hello,

In the beginning, it's easy to add details that will make your model more complex later in the modeling process. I think I realised that. And it's kind of different for every software.

I put too many zones in my building... it's easy to do so in Openstudio. Don't you think?

Down the road, I think I am hitting the maximum performances of my PC.

1st set of questions:
#1 - If a model only occasionnaly CRASH, is it a good indication that the PC is not powerfull enough? last night a model crashed, I rebooted the PC to free RAM and it went through this time.
MAYBE that the output file are too big: 1Gb .SQL file / 1,6Gb .ESO file... my PC has 2Gb RAM. I have a feeling PC may crash if I don't have at least that space in RAM, no?

#2 - Can I trust the results of that successfull run (if it has crashed in the past). I suspect that if a run goes through without crashing, it probably means the results are good, right? 

AND WHAT ABOUT YOU?
#3 - What kind of PCs are you running. I consider upgrading. I have an Intel Core2 Duo CPU 2,2 GHz with 2Go RAM running on WIN Vista Ultimate.

#4 - Should I go for more CPUs or more RAM or Both... I understand from the old msgs on this forum that E+ is single core but there are plans to make it multi-core, right? I should upgrade to 4CPU's then. I think I'll go for a Intel Core i7-2600 Processor (3.40GHz, 1066MHz, 8MB) with 4Gb RAM

I have a second set of questions regarding my "complexe" model but I think I'll post them seperately in another msg. coming next!
