From now on, I will only answer BIOS pref questions that are prefaced with which modchip and mobo version you're using.
Reason being, I don't want to keep repeating "if you have a 1.6" or "if you want to mod your BIOS", etc...
How does 4983 stack up against iND? Go check it out
, and see that there are some pluses and minuses.
Not to overgeneralize, but the X2 vs. iND thing in my mind it kind of a Windows vs. Linux thing. You can mod an iND BIOS (if different ways but with the same results) just like an X2 BIOS. Just how much work to you wan't to put into it?
Frankly, to go on record for about the 100th time (and since your asking about an X2 bios which proves to me you don't have a 1.6 mobo), prefer 4981 to 4983 because you can't mod 4983.
So, go find out if you're comfortable with the iND bioses. If you have to ask someone else for their opinion, I'd say stay in the X2 comfort zone. If you don't understand why, go read that link again.
Finally, I ain't bashing the iND BIOS. If it works for you it works well enough. I'm lucky enough to have access to mountains of 1.0-1.4 (at the latest, and those are rare) boxes, so I don't have to worry that Evox is the only team to have a 1.6 compatible right now.And I'm getting pretty sick of people flaming TeamX for not having one yet, and focusing on the 4th gen right now. Have a little fucking faith, guys!
Edit: @SGM, I see. And I hear you. But you gotta be careful recommending an X3 to a noob using an A-chip. Some guys (not you onesikgypo) are just dumb enough to try it (heh, even though at 1025k it ain't gonna fit..
