Before considering upgrading to a 5950u or any other moded bios, it is most important to establish how high the card overclocks with its original bios !
The idea being that you must first set any new bios's stock core and memory speeds no higher than your card's known max levels. That way, no matter which bios you flash, there should be no problems with booting and installing drivers. Then of course you just overclock to the new bios's max levels !
Also, before doing anything, I suggest you have a good read of other peoples experiences in the two linked threads below,
