I plan on overclocking all of em too. Bring the memory bus down and up the core clock, increase the voltage. That's what you wanna do right? Of course be safe, but that is the method to get the most; correct??
Might need to make sure you will have proper cooling, especially if they are going all on the same mobo. Mine are in an open environment so are not that bad, but I have a fan on my 5970 cause that thing will get LOUD otherwise.
I was planning on running 4 in mine, but I feel best that I just run 3. Even with coolers on them the middles ones just couldn't get enough airflow.
Did you pick up those Visiontek ones for uber cheap? I thought about buying 1 or 2 of those but I don't dig reference coolers anymore so opted out. :-/
When you game, if you game, just enable crossfire when you game. With those cards, you don't even really need to crossfire unless you are running eyefinity.
Indeed I did. I paid 370 for each card. Got them off of tigerdirect.com via slickdeals.net
I really don't mind loud. I'm a bachelor and loudness has never really been an issue with me. I live in an apartment and my computer is about six feet away from the air conditioner. Helps keep it cool. I'll set in trixx to have a set fan speed. One that isn't too loud with four cards but at the same time keeps them cool.
