Is it worth rewriting forum URLs as static links these days?

I was going to hack my forum code to show the link of /viewtopic.php?showtopic=45 as /viewtopic.php/45

This use to be very beneficial when optimizing a site for search engines, but now I'm hearing arguments that this is no longer the case. I also learned that Google will spider dynamic links slower so not to tax the sql server.

It just seems to me with observation that Google still prefers static links even though it will crawl and index dynamic links. So I thought maybe a compromise would help. Instead of rewriting the thread links, I would just rewrite the topic links, so /index.php?forum=26 would look like /index.php/26 That way the main topic pages would be updated more often in Google's index, and would link to the dynamic thread links.

Thoughts?

Having one or two parameters is not the problem and so rewriting them is not what i suggest but there may be other opinion also.

i hear a lot of talk about doing stuff like this to improve rankings, but i think the search engine is getting better. i can even give you an example for my site. if you do a google search for yetti olypics my website forums show up number one. and if you ask me dirtymonkeys.net/forums/viewtopic. php?p=49&sid=3f092f1bd5b5505a07326295aecb1e8 is not a very search friendly url. i also figure there has got to be a bit of competition for that search. if i could get number one for yetti sports that would be something else.
