Depends on what you mean by good. I'm running a Pentium 4 mobile right now with windows 7 32bit and I say it's good because it can still do web browsing pretty well. 😀
Well it came out in 2009 and it is a Celeron processor. Is it still good in 2015? Well it isn't very special in 2015. There are many many many processors that completely outclass that processor by more than 3x. Is it still good today for browsing on the internet? Definitely! Is it good for playing games like Battlefield 4? Not at all!
