thanks again for the replies guys.first off both of my 2 main cards, the lexar 8gb and transend 16gb work great in my cam with the 600x being a little faster when i shoot in rapid fire like 50-60 picts in one shot,its just gettin them into my pc...i have a custom built pc that a good friend built for me from the ground up with lot of memory and speed...the only down fall so far is my pict down load speed, thats why he told me to try the firewire 800 deal with no speed gain lol...so i just dont know what to try next.... rod
