Good Gaming PC?

I need suggestions on a good gaming pc. i want to be able to play games w/o lagg, my computer now is okay but i want a better one.

Also want to Vid on rs and things w/o lag, yanno ? my budget is 250. help please.

 

Your not going to get a "good" gaming computer for 250$. Even a junk laptop will run you 500$.

Increase you budget to around 600$ and you can get a half decent dell desktop. If your looking just to play runescape just get a good internet connection and it will run smooth.

 

You should edit your post and include your current stats of the computer so we can know what you need to improve on... if its just graphics buy a graphic card .
