to answer your question, yes; It will be a tight fit though.
To calm your nerves, i did saw on Alphas' list that the Soyo plus was included on the boards that can work with the 8045; the older soyo dragon didnt.
Hope that helps
BTW im kinda lazy to send you the link, but you can search for the 8045's and see what comes out...or someone who isnt lazy will probably provide you with the actual link.
