I suppose calling it 'Tech Support Forums' or 'Tech Support Board' is out of the question? Personally I think that the title should relate closely to what people actually search for. If users are cute enough to type 'tech support' or 'technical support' into Google (and they are judging by the figures I just looked at) then why wouldn't they click on a result with that title in the SERPs?
I'm not too fond of converting with the page title - I know it can help, but I think the snippet is the better place to do it.
BTW rough guestimates
'get help with computers' -> negligable volume
'tech support' || 'technical support' -> ~12k per month.
'computer technical support' -> ~12k with far less competition
