As was already touched on, no, 1.73GHz quad core is not like having a 6.92 GHz CPU at all. Not even close.
A quad core processor (or any processor with more than 1 core) is only going to be fast in tasks that take advantage of the threading horsepower. That is to say, if the game or program you use only uses one or two cores out of four, you lose efficiency and speed on your quad. Fortunately Intel and AMD engineered their chips to throttle themselves up accordingly in those situations (say you have a program that only uses one core, the maker throttles the other cores down and overclocks the single core to the thermal design limit of all of the cores combined, to give you high performance in that single threaded app). but if you have a program that uses all of the cores, they run at their stock speeds (sometimes slightly faster) to achieve the maximum performance based on heat and other factors. I'm going off on another tangent entirely, but I thought it might be helpful for you to know about this aspect.
Don't read too much into the whole "CPU speed requirement" because in all honesty, game companies have to subscribe to the greatest common denominator when it comes to speccing their software out. Another way to read into it is to see if they said "2.5 GHz required (or even just recommended)" and then they'll say "quad core" or "dual core". If it's dual core, then you're fine with a quad. If it says quad core, then be aware of it.
In all honesty, if you're that concerned about it, tell us the games/software that you're seeing this on, and what they say, and we can tell you for sure how it will do on a given architecture.
