Hello 
  
I emailed the main OFF site and was advised to come to this board and this topic. 
  
First my new machine (as opposed to the Horror from HP).  The CPU is an Intel Celeron E1400 2GHz dual core.  My computer tech said it would run equivalent to a 2.6 GHz single core processor.  Memory is as large as I could afford, 2GB.  The Vid Card is an MSI NX8400GS 512 MB "Dual Core Cell" that various applications have read as a GeForce. 
  
Now, because I read what people say about their flight sims, I see that OFF is supposed to require a 2.2Mhz dual core.  Except I was informed that OFF does not use the dual core processor but needs the processor's over all speed.  At least I think that's what I am being told. 
  
Me I'd just like to know if it will run.  On my old machine  (Celeron 2.5 GHz, 2GB, a 252 MB Radeon 9250 with a PCI bus) the most complex planes for FS2004 had trouble exceding 10fps.  Now they run at 30-50fps.  The stock planes ran at 20 + now they run at 75 or so.  CFS3 was better by maybe 10-15%. 
  
I haven't understood much about computer structure since DOS and the 386SX. So I don't one CPU from another.  And dual core as far as I now is two CPUs linked and working in tandem. 
I've been told in effect "you pay your money and takes your chances." Not a very encouraging answer. 
  
So if there is any collective experience out there that might help me decide, I'd appreciate hearing it.  Not too jargony though, I don't know much about vid cards or CPUs I just know you need quick switching and Memory for cache.  Of course I may be wrong about that.
