Noob SLI question

[straxusii]

Sorry if this has been answered before guys, had a look round the board and couldnt see the answer.

I've decided to jump from AGP to pcie at last. Im going for either a A64 4000+ cpu or dual core and have pretty much decided on x1900 xt as the graphics card (AA+HDR being the deciding factor really).

Ive got 2 questions:

1. I guess its ok to buy a standard x1900 xt now and then at some later stage I can buy a crossfire edition x1900 to add to the system?

2. I guess I have to buy a crossfire motherboard? (and presumably these work fine with just 1 graphics card initially)

TIA

Although regarding your first question I dont think you need to buy a crossfire edition x1900 xt basically 2x x1900xt = crossfire.....

Ah so does the crossfire motherboard essentially negate the need for a specific crossfire edition graphics card to achieve SLI?
