Just keep in mind that responsive does not mean mobile friendly. The theme you linked is indeed responsive but not mobile friendly at all. You still have to tap very small hyperlinks to open threads and such.
When it comes to SEO, tables shouldn't have an impact on it. What matters is how the important data is displayed in template. (such as <p> for paragraphs, <h1>/<h2><h3> for headers, etc.) Sure vBulletin 5 might have better SEO but since you stick with older software there's not a whole lot you can do about it.
