Hi,

I've been gaming on my PC quite a bit recently and where my on board graphics chip is really good on my computer, I want to be able to play games at a level with higher graphics and no lag on a HD 1080 X 1920 display. The dimensions of the computer are 105mm x 360mm x 305mm (4.1" x 14.2" x 12.0"). Here is the link to my computer http://www.lenovo.com/products/us/tech-specs/desktop/essential/h-series/h520s/. I don't want to spend more than £300 but It's possible that I would buy one for almost £400 if it's worth it. Thank you for any help or advice provided,

Joe
