There are several issues here that I feel needs to be addressed first.
First of all: using a 32-bit operating system you will be limited to maybe 3.5 GB of RAM, and so won't be able to use the full 4 GB.
Also, in many cases 4 GB of RAM will be slower than 2 GB of RAM because you won't need it but the memory controller still has to keep track of it and so just slow things down needlessly.
Another thing: you're getting a new motherboard, a new processor and new RAM but still upgrading into a dead end system. Is that really a good idea? Sockets generally have little bearing on the price and you won't really get away any cheaper going 939 than AM2.
Oh and AM3 has been put on the back burner and the next socket is going to be AM2+, which also will use DDR2. AM3 won't probably be out in 2 years time if ever. Most likely you'll have to upgrade to DDR2 sooner or later anyway.
As a side note: There are some motherboards with both AGP and PCIe slots. That could offer a upgrade path worth considering.
