I know I am late to this whole party, but Gold is -not- a better conductor than Copper. And there is no conductor better than Silver. But, as with anything, real-world constraints have to be taken into consideration... and Gold does -not- corrode, at all. That is one of its properties, is it is -extremely- non-reactive. Thats also how one can harvest it as we can see Foxvir has done here. Strong, caustic acids, that are highly dangerous to many many things, cause no harm to Gold.
The problem with Silver, and even with Copper, is corrosion... they both can react with Oxygen outright, and many many other things. Ever seen Copper that has been near Sulfur, even as a gas? And when talking the pins on a CPU, or some of the connections within it even, where even a TINY difference in conductive properties (adding resistance, for example) causes un-desired operation... yea, Gold gets used to prevent that from ever happening, and guaranteeing that the conductive properties of that pin never change.
And the reason we dont use Silver in wires, well, is obvious... too costly. And also, on the topic of conductors and their properties... Copper is nearly TWICE the conductor that Aluminum is... Yet Aluminum gets used, simply because of cost.

Since the mid 80's building codes were changed so that you are only allowed to use copper inside of homes. Before that was copper clad aluminum wires, but aluminum wire tended to cause fires because of its higher resistance, so the code change. Steel or an aluminum alloy are used on all the power lines though.
Gold is $1349/troy ounce, Silver is about $29/troy ounce, but silver is actually rarer than gold. Oh, and copper is only $4.58/pound

Hehe, yep... well, there are other properties of Aluminum that make it a poor choice for house (customer end electrical equipment) wiring. Namely, you can tighten it all the way down under a lug, I mean, really put the screws to it... and come back a week later and it will be loose. That is because, in layman's terms.. the metal 'tenses' up under that pressure, only to relax later over time, and take the shape of whatever it has been torqued down into. This will go on until the Aluminum has changed shape to match the recess in which it is in. And if a connection is not mechanically secure, it is not electrically secure... That is, there is higher resistance, and higher resistance equals more heat, more heat in an enclosed space, means bigger chance for fire.
286 was LLC (sides pin) http://www.cpu-info.com/index2.php?mainid=286
It's Pentium I and I can see a 486 too
