I agree with Draghermosran the Dell ones are the less expensive. Plus their hot line is free.
You can have a look at their web site dell.com
I have one since 5 years and i never had big problems with it.
I think to buy a new one too for playing RRR and DD2.
But 961,5 dollars is not enough to have a good processor and a good graphic card to play games.
You need at least 1500 dollar.
Wait for your Christmas presents to get a little more money.
