Intel D975XBG bios question

Hi everyone,

I would like to know before i buy the intel d975xbg if the bios has its own o.c. utility (couldn't find any info on it) and if it would support 2-way sli with nvidia geforce cards like gt 200 series or up. I know that one is pci express x16 1.0 and the other is pci express x16 but runs x4 electronically. If anyone on the fourm that has the mobo and can tell me or can answer this. I would greatly apreciate this.
thankyou
