Question about motherboard

[N1CKH0LAS]

Hey,
I'm wondering if the bus bandwith have any major impact upon kHash/sec, when using 3 video cards ( 7950s). For example, is there any big difference between this very expensive motherboard "Asus Rampage IV Extreme " and this cheap "AsRocK H77PRO4-M Socket 1155" one ? I didn't include links because this may be considered advertising or something, so you have to google for specs.

Also, i'd like to know what's the expected kHash/sec while mining LTC if i'll be using the cheap "AsRocK H77PRO4-M Socket 1155", 3x 7950 and all the other components "standard" as recommended into the thread https://bitcointalk.org/index.php?topic=163306.0

Thanks in advance for your answers

No.  For mining, most GPU will run off a 1x slot, so if you don't mind using risers any old cheap board will do.
