Advice on a New Video Card for a BH6

[Mike D]

I have a BH6 v1.0x (this is the original revision) with an agp 1.0 slot (don't know what voltage it's keyed for I'm assuming its 3.3v because its agp 1.0). My question is what modern cards can still use agp 1.0 slots from the original BH6 era. I'm leaning toward a kyro 2 or an nvidia gts or GeForce 3 but am afraid they won't work or even fit in my agp slot. Does anyone have this board and tried one of the above cards? I want a card that I won't have to replace when I do a full upgrade but would like something better than what I have now. Thanks in advance.
