I'm thinking of getting Dark Souls 1 on steam. In requirements section it says: Processor: Intel Core 2 Duo E6850 GHz+ or AMD Phenom II X2 545 3.0 GHz+ Video Card: GeForce 9800 GTX+ or ATI Radeon HD 4870+

I have laptop with Intel Core i3-3217U @ 1.8GHz and NVidia GeForce GT 710M. Would I be able to play it without any problems?

No, your processor is way too weak
