my laptop-
hp pavillion 15 notebook pc
processor-intel core i5 4200 cpu @1.6GHz
ram-3.78gb
gpu-amd radeon hd8670m/ intel hd graphics family
os-windows 8(64 bit)
I tried play current high graphics games( like batman arkham origins,nfs rivals, nfs most wanted etc.) at max or mid settings. but they ran quite badly. and I have told by many of my friends that my gpu is not good enough. so i want to know that can I change my gpu to a better one? or it is not possible for laptops?
