Quick SLI question

I just realised… perhaps I could get SLI on my new rig :smiley:
If I got this mobo:
http://www.techbuy.com.au/products/53429/MOTHERBOARD_FORAMD/Gigabyte/GA-K8N-SLI/GA-K8N-SLI_nForce4-SLI_S939_DDR400_PCI-Ex16(x2)_SATA-II_RAID_GigLAN_ATX.asp

and two of these:
http://www.techbuy.com.au/products/53273/VIDEOCARDS_GEFORCE_PCI-EXPRESS_SERIES/Sparkle/VGSPPX43LC3L/GeForce_6600LE_128MB_HDTV_DVI_PCI-Ex16.asp

Would it:

  1. work?
  2. be worth it?

And would I have to buy anything else? It says you only use the little ‘SLI connector’ thing with 6600GT’s and above…

Thanks :smiley:
