I've used Postgres out to the terabyte+ range with no probs, so it all works fine. Of course, whenever you approach huge data sizes like this, it tends to change how you access the data a little. eg. Do more threads equal more user connections, or more parallel computation? Generally though, databases aren't really hindered by CPU, instead by the amount of memory in the machine and this new instance is huge. No idea about MySQL, people tend to scale that out rather than up.
