Don't get that 4670! It is PCI-E.
Only AGP cards are able to be installed into the ASUS A78NX-E...
I have that motherboard and currently I have an ATI 2600 HD Pro.Best upgrade for us is the 3850!
Check the performance results on the 3850
and it beats the 4650 out of the water. I also compared other AGP cards to find out the best upgrade. I am about to order that 3850. Here's some links for you:EBayAmazon
