I have a similar issue. I want to change my motherboard (original Gigabyte 965P DS3 rev1) but there's no point, or is there?
I have a 4870X2 so would I benefit from a newer PCI-E port? Would I get a better OC?
I have filled all of the ICH SATA slots and really don't want to use the JMicron slots
But is there a point to going for an i7 rig?
