A three-GPU SLI?

thanks for the getting back guys, i went ahead and got the silverstone.i found it at a place i saw someone in the forums talk about. its called eastluna.com and it was 152 bucks shipped. hope they are as fast as the "egg"

also as a follow up last night i played half life 2 for like 2 hrs with everything cranked up and system runs fine,just didnt do much in 3 dmark06 compared to 1 card and when i try to oc cards it shuts down.could it be the second card is just bad?

www.overclockers.co.uk says:

"These cards require PCI-E x16 slots, they will not function in a x8 slot so for SLi you need dual x16 mainboard. Finally 500W minimum for PSU and 600W+ is recommended."

its not an article but a note in all the geforce 8 series cards they sell
