somebody told me to buy GTX 660ti. Is it a good option ?
if its the max budget you can afford it will be okay, but if you can go a bit further i suggest you get a gtx 900 series card or an AMD 300series card.
You could get a GTX 960 or an R9 270X (or R7 370) and that should strike a balance between CPU and GPU. Any lesser GPU and it'll tip towards a GPU bottleneck.
gtx 760 or an r9 270 . do i need to overclock my cpu for these kind of GPU's. @ Jomari Gonzales
if you feel like you need a bit more power on your CPU especially CPU intensive games/tasks then do a mild OC, make sure it stays on an acceptable temp
so what do you think ... which gpu i should go for ? what would be the best option by which my cpu dont struggle @ Karan Thakur
i think you should upgarde to gtx 650 ti and later when you have money upgrade your cpu to fx 8320 or 8350
this way you would be able to play battlefield 4 at 1080 p high settings smooth frame rates, even witcher 3 would run at medium settings , gta v at medium settings, but you need to upgarde cpu in future , and the gtx 650 ti is an external graphic card as you know well its not a integrated graphics card so it can later be used on other system in future.
With existing cpu and gtx 650ti you would be able to play battlefield 4 at low to medium settings.
