Hi, Guys u can check my system specs in the attached dxdiag screenshot. Currently I have NVIDIA Geforce GTX 460, but I installed it like 2-3 yrs ago, and now when I play games like arkham city, the game crashes like after every 5-10 min. when I play Assassins Creed Revelations Multiplayer, I get lag not due to internet, but system performance. Could you please suggest me some good graphic card. I have never used ATi cards, so have no experience in them so I prefer nVidia. My budget is 100 GBP. but I can stretch to 125 GBP. at max. Please respond soon. I want to buy and install a new graphic card before arkham origins is released I.e. 25th October . Other games I would like to play are Assassins Creed Black Flag, Watch Dogs, Castlevania 2, Thief etc.
