well I can do up to about $325. And the last time I did not go with the latest thing, but got what other people had and liked it was the Voodoo3, quickly out of date and now pretty much unable to play MOHAA without great disadvantages - even with all the fixes for it I can not see a sniper at the end of the hazy street but he can see me clearly - so I don't have a problem getting a ti 500, especially since I want the TV out and all that. But I do not know what those acronyms mean and if some are more desirable than others, or if they all have them but only some mentioned them in their description on line etc.
