You did select the 2nd device when you tried to OC the 2nd card?
Why does clocking from 750 to 770-790 seem to make no difference or even score less (with CCC) ? I dont think Im cpu limted that badly at 4400mhz.
You shouldn't be CPU limited in almost any games/settings worthwhile with a pair of those cards. Can you give me some numbers? Like Crysis at high settings or the like. It sounds odd that the cards perform worse at a higher GPU clock.
Is it hard to flash the cards ?

No, but honestly I don't really trust the RBE BIOS Editor to mod BIOS'. I do it manually in a HEX editor. Flashing is simple if you look up how to make a USB stick bootable and read a bit about the basic commands of the flashing program. You can flash cards in Windows I think, but I use DOS because it is considered safer. Just make sure you get the latest ATIFlash and check if the BIOS you are trying to flash is 128kb in size and not 64kb.
