@dark-energy: is that 4850 512mb version? what are these "other" games? and are you trying to run at ultra high settings and ultra AA settings? imo no point investing in i7. and 5850 oc to 5870 speeds pretty easily... though i think it's the extra vram gonna make you feel a playable difference.

@frogeye: just use atiflash and save your original bios, mod it with RBE v1.24, save new one, flash card(s).

my question: i've seen some people with ridiculous high mem clocks like >1300. is that reasonable to expect? on my cards i'm thinking it's the mem clocks that it's not liking. i've bumped core volts up and i can get core up to 950 at 1.2v (could probably go lower volts) but the mem doesn't seem to like going above 1225ish before crapping out.

edit: i have 5850.
