|"Firefox is NOT faster than IE7, in fact it is much slower opening."|
That's certainly the truth, IE7 comes up in a flash, even on 256MB of RAM while Firefox takes forever on the first load.
"I notice that my max is: 1536MB
... if I put in another 512MB that should run IE8 without any issues shouldn't it? that would take me up to 1024MB...."
Well, you should be able to run IE8 fine with 512MB, even 256MB. M$ will tell you this on their website.
"...but do I need to worry about heat issues then with that amount?"
I didn't know that you were having heat issues. Mind detailing that a little?
