Don't get me wrong, it still is an excellent machine. But the prospect of over double the multi-core performance and 1.5x the single-core performance, hopefully equating to close to half the compile times, is tempting. Wildly better GPU performance would also be useful now and then. I'd also take the opportunity to get more RAM (16GB is usually enough but not always) and more storage (1TB is sometimes a bit tight to be honest and I find myself uninstalling things to make space for other things).

Do I need it? No, of course not. But could I make use of the extra power? For sure.

And shiny new things are fun.
