320-2x vs 320-2e

I'm having a hard time deciding which one of the two. The motherboard is a K8WE which has two 16x PCI-E slots with SLI support. Would there be enough difference to go with the PCI-E version or it's marginal enough that the PCI-X will be just as fast. I guess my question is would the 320-2e worth sacrificing SLI?

Both of these cards should be limited by internal bandwidth not external interface so the performance should be nearly identical between them.

UICompE02 can probably better determine if there are any major differences. Personally I would go with the pciX version because it does leave the possibility of SLI open. So unless the pciE one is a bunch cheaper I would get the pciX one.

Well, the PCI-E interface will really buy you nothing on those since it is actually bridged from PCI-X to PCI-E in that case.

However, that board doesn't have PCI-X slots, correct? If it only has conventional PCI slots, you'll be limited to 132MB/s over that interface. In this case, you will be able to take advantage of the extra bandwidth that PCI-E has over conventional PCI.

K8WE has one 133 MHz PCI-X and two 100 MHz PCI-X slots.

K8WE has one 133 MHz PCI-X and two 100 MHz PCI-X slots.

Ahh, I was thinking of the wrong board then. In that case, I'd go for the PCI-X version since PCI-E won't really buy you anything. That is, unless you plan on moving this board to future systems that may not have PCI-X available.
