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.
