I have a DFI Lanparty NF4, so technically have the SLI capability... but is that worth it?  I play mainly WoW with some Quake 4 but want some wiggle room for newer games when they come out.  I currently have a 6600GT.  Want to budget $100-$150 right now.  Two DVI slots would be nice as I plan to go dual monitors soon.  Any suggestions?
