Thank you all for your responses.... I am assuming that these suggested video cards will automatically be good enough for Windows 8. Correct me if I am wrong?
Btw, how should I go about finding the optimum video card for my system by myself? Any tip is welcome.
Entry Level GPU would do. 6450 maybe. But I would consider a whole system upgrade, to an AMD APU or intel with HD graphics.
Will consider that in future!! My laptop is just one year old , so right now I won't be able to spend much.
