I building a new system, should i use my X1800XL, go sli, or go Cross fire?

[necro007]

The mobo has to be a DFI.

The thing is i already have a X1800XL and i don't know if i should:

1... go crossfire

Or

2....go sli

Or

3....Just use my X1800XL

Is cross fire any good? Also i would have to spend much on going cross fire cause i already have the X1800XL.

What do you think i should do?

Any help would be great.

since the mobo has to be dfi, wait til dfi releases their rd580 board (should be by the end of the month), and see if that's a favorable board. if it is, get that board. if not, go for one of their nf4 solutions.
