All those 8X cards run... at 4X in the 4X slot.
There are some badly written manuals that confuse people and I can't fix that, but here's why the 8X cards work in 4X (and other) slots. If they didn't, they couldn't sell them.
I do want to comment that you want to have plenty of power supply Watts and good case cooling when you fit high performance cards.

My computer is:
Intel D850MV motherboard
512MB RD Ram
geforce 2 mx400
i'm thinking of changing a new graphic card but nowadays all the graphic cards are AGP8X or PCI-Express. My motherboard only has AGP4X. What should i do?
I did think of changing my motherboard but then my RD Ram will be wasted. Any suggestion?
