If u are not a gamer why do u want a SLI mobo.... when u are not willing to purchse even 1 graphics card why do u want place for 2....?????
get ASUS A8N-E it has less features than the SLI version but is based on nForce 4 ultra... and is also quite feature rich, moreover it has 4 PCI slots so u can always add things ic u want..... with 10 USB ports u will never have to waste a PCI slot on usb etc....
this will be much much cheaper tha the SLI version and also good at the same time
another good option is DFI Lanparty UT nF4 Ultra-D, see if u can get.....
