I would go for Yosemite but thats my personal preference. If there are features that you will use in Yosemite then its an easy decision, if you are happy with Mavericks features then stay with Mavericks, I like both but Yosemite has some great additional features, with the new Photos app being released in later updates.
If you reinstall Mavericks then a full format would be a wise option. If there is anything that you would like to keep, back it up first as it will save you downloading it after the install.
Either guide will work for you, I used the guide from the top of page, remember if you upgrade to take the steps documented. I'm not sure if your audio codec and ethernet are the same, but you will know this already as you are using a different motherboard.
Great thank you!
