I made a maiden visit from the UK to Ireland in April. . The city of Dublin is filthy and nothing in it. Expensive like hell.
There is nothing out there apart from reflections of the British again screwing up a country. I visited places like Killaneary and Cork county but if you have done Scotland then this a poorer and ruder version of that. Dublin is very expensive for no apparent reason and the Irish need to learn manners starting from the immigration officers. So if you are visiting the UK for the olympics please give Ireland a pass and you are better of spending it in seeing better places rather than burn money !
