hello about a month ago i got a 5850. XFX XXX edition. now i'm trying to go Crossfire / Eyefinity. i've got the monitors, dongle, and a second card ordered my question is in regards to the bios on the new GPU. The first one I got was as I said the XXX edition. only there are no more in stock and no estimated arrival. so i got the regular edition instead. the main difference between the two is the regular edition can not be voltage unlocked. in order to OC the XXX one, I had to up the voltage. running in crossfire will mean I won't have to OC for awhile - but come on, i'm going to want to I had read in the reviews for this card, that someone flashed the Asus 5870 bios. that got it working for them, able to unlock the voltage and change it with software. so my question is - instead of using the 5870 Bios, would I be ok just reading the bios off of my XXX edition and flashing it onto the new regular one? I would rather flash XFX to XFX, as well as keep it in the 5850 line if possible. though regardless of possible or not, i'd want to do what is recommended (once we get over the fact that I am going to flash such an expensive card). so what's the way to go?
