Im going to buy 2 1GB Palit GTX 460's in sli and 4GB of DDR3 1333mhz RAM and was wondering whether a X4 955 will be enough to ensure no bottlenecks. If not then what do I need?
no, it will not bottleneck if you have a motherboard with at least 2 PCI-E slots running 16x - 8x or 8x - 8x, once you delve into 4x on the PCI-E slot, you see notable performance hits...
