It looks like the Asus K8T800 board, which I'm getting is $140-$150 depending upon where you get it, and the 3400+ is $400. So, around $550. But, I also ordered some dual channel Corsair TwinX DDR400 with the new coolers for $248 and my new dual radiator/gpu block/Swiftech cooling parts for $325, plus I bought a new ThermalTake XaserIII case which was $133. I know I dumpted a ton of $$ into my new system, but it should be well worth it, especially when I get my hands on overclocking it
