Will single gtx 460 1gb work in newer AM3 boards

the only thing sata3.0 might effect is when they ise one pci as the gate for it, but this should not effect the pci express slots on the board esp the primary pci-e slot. if you are planning to do a single gpu there shoudl be little impact as most boards even when they do go from x16 to x8/x8 with multiple pci-e gates being used suffer only a 4-5% performance loss and thats with very high end cards such as a 5970 , in a 460 i doubt you'll saturate the x8 line at all

so in short no there shouldn't be any conflicting issues

So the single nvida sould work fine as long as I dont try and sli even tho it will be a crossfire motherboard?

yes you will be fine running one care... now you can hack a am3 board for sli but thats a tricky procedure involving steps even most enthusiasts would not be comfortable with and that would needless to say void your warrenty
