hi all
i am getting confused in between two product

1 gb DDR3 NVIDIA GeForce 315M

And

1 GB ATI ROBSON XT DDR3

which one os better

The answer is ... it depends. It depends upon what operating system you run, what type of software you want to use with it, etc. Myself, I like nVidia, but principally that's because I mostly use Linux and there are better drivers for nVidia on Linux than for AMD cards. If you are just a "normal" user, then either will serve you well.

i am planing to buy laptop and i will use windows7 oprating system and my use for graohic card is for gaming and as i am software engineer so there some times there is need for graphic card for some events
