.info Domain Name for PPC Landing Page???

Has anyone noticed any difference between using a .com domain versus a .info domain for landing pages for PPC campaigns? I would think that the keywords in the name would be a bigger boost than any drop because of the .info qualifier.
Alternatively, I could do a subdomain on an existing website:

Quote:

www.mysite.com/newkeyword

Any ideas? I’m wanting to try out PPC on one of my better performing articles but the cheaper I can do it, the better (multiple domains).
