Hi, some how I got my hand on Lenovo edge 73 with i5-3470, 8GB RAM and 500GB HDD. Now I want to put a GPU for the gaming. Please suggest me which GPU to buy as I have budget of just AED 600 ($ 165). I have a 19" LED LCD (1366x768) so for time being i wont be playing high res but in near future will buy a 32" LED LCD so need a proper GPU for that. I'll be playing mostly BF4, COD Franchise, Bio Shock stuff like that.
