Okay, I'm a relatively new at building systems. I've got an order in right now at Newegg and it hasn't shipped yet, so I can still change it if I need too.

I ordered a Phenom II X4 940 Black Edition, and I'm not sure if the motherboard I ordered is going to work. The mobo I ordered is an Asus AM3 board (M4A78T-E). I've now noticed that said CPU is for an AM2+ socket. Will this processor work with this mobo?

Thanks in advance!

No, it won't work. AM3 processors work in AM2+ motherboards, but AM2+ processors don't work in AM3 motherboards. There will be a new 945 processor that will work, but it isn't out yet. Also remember that you'll need DDR3 memory with the AM3, but only need DDR2 with AM2+. I would sell either the mobo or processor. Cancel the order if you can.

That's what I was afraid of. It's now too late to cancel the order, but I can return the items to Newegg.
DAMMIT!
Now I don't know what to do! I could either order a different mobo for the CPU, get a lesser PII X4 that IS an AM3, or just scrap the whole AMD idea and go with an Intel.

Well you could get a worse one, because I'm assuming you're getting a black edition to overclock, so you can still overclock the 910. The X3 720 is black edition to, I don't know if you care about the number of cores that much.

make sure you look at memory prices also. you can get 4GB of DDR2 memory for less than $40, but it's around $100 for 4 GB of DDR3 that goes with AM3 mobos.

And intel is always a good idea.

Regarding the memory, I've already got 8 GB of DDR3, so really the 940 is pretty much a lost cause at this point.
I'm P.O.'d at myself because I thought I had this figured out. Part of it was due to some bad info from a coworker. Oh well.
I think I'll just send the mobo and CPU back and go for an other Intel setup. Now I just have to figure out if its going to be a Q9650, Q9550 or an i7 920.

As paranoid said, AM2+ chips will NOT fit in AM3 sockets. But AM3 chips WILL fit in AM2+ sockets.

Send it back and wait for the AM3 quads, or get a X3 720 now and overclock.
