[Opensim-users] Streatching Opensim to far?

Ok, to let you know, I am on the East Coast, lucky to have a cable 
connection to the web with 30 mbps download and only 3.80 mbps upload.  
I am legally blind with a kidney transplant and can't afford another 
machine.  My imune suppressants have many side efects, mood swings, 
alergy to sun light, and fluxuating blood sugars.

I don't go out often because of all this, so any extra money I have left 
goes into my computer and internet.  Nothing else fun left to do.  I 
live in my oomputer in a way.  All I can imaging is trying to max the 
efficiency of one machine, my wife has her own.

And from what I read the am3+ broke over clocking records.  Maybe with 
an additional 1 TB solid state drive for faster assetts wouldn't hurt 
either.
