HIya bud! Are you looking to build your own or buy a pre built one? Building your own you will definitely get you more bang for your buck, and probably have fun in the process. These days pcs aren't that hard to build, there's plenty of youtube videos showing step by step how to do it.
Then there's budget, we would have to know your budget to give you a good build for what you are looking for.
Not being rude, but this section of the forum is generally for attempting to resolve issues.
It may be better to move your post to General Discussion
Also posting your current sys hardware components would help.
