Hi. It’s a perfectly capable machine, and is decent enough to play games. It’s obviously tech from a few years back, so it depends what you’re comparing it with I suppose. It has a dedicated Nvidia mobile graphics, so would be better for games than one that just uses a non dedicated GPU. There are reviews from back when it was released that would give you more details.
Screen resolution is also subjective, this resolution was more standard back then, and some people prefer it because it makes things easier to read and in general icons/windows etc. are more a normal size, as opposed to a 1080p/1440p resolution on a small 15″ where everything becomes very small. There is no bluriness, as it’s the screen’s native resolution.
