Hi I need a new tower as my old one is struggling. I have a monitor and such. I would like a computer that can handle latest sim games not bothered about massive multiplayers and it would need to handle my graphic tablet with no lag. Budget is £600 - £700. I really need help as my medication is making me get confused easily I just found I made the mistake of ordering one with a 6 year old cpu without realising. Thankyou for any help in advance.
