dude, that thread is about the x800pro -> x800xt
These are completely different senarios...did a search in that thread and nothing mentions a x850. Those are very hit and miss to mod. I could have told you that, I spend weeks last year trying to get x800pros to mod lol...drove me nuts :haha:
Hey, I don't blame you at all for going for the XT, to each his own. I got this card for $200 and it kills the x800xt PCI-X in my girlfriends rig, so to me it was well worth it. If your willing to give it a shot, I think the odds are well in your favor, and I think you'd be very satisfied
Anyway, I don't want to debate it any further, starting to clutter this thread. The info is out there, just search...and search more then this site. I didn't find out that the flash could be done till 2 weeks after I bought the card, did a random search on google, and found the information on another site. Shoot me a PM or ask away on my sticky, I don't want to clutter up this thread for ya
