Actually, Perrin already answered the question :)
And now for my 2c. All other things being equal, I would opt for a more
ram over a faster CPU. The extra ram can be used to reduce the load on
the CPU through judicious caching and whatnot, but if I needed more CPU
cycles to serve 60K pages, I'd be worried about how many more requests
it would take to saturate the new CPU.
In other words, I would gamble that extra ram would be sufficient. If
I'm wrong, I'd have to address the underlying problem, but at least I
would have more ram to work with when doing so.
That being said, what does 4G vs. 8G comes to what/mo for a dedicated
server? Say $30/g *4g * 1.25%(profit) = $150. And assuming a 12 month
payback on the hardware, that would be $12.50ish/month more for the
