The nVidia GT 435M is a great midrange card for a notebook computer. If you are looking to do some gaming, school work, travel, etc.. it will be perfect. However, if you want to play bleeding edge games with all the settings turn up as high as possible, you would need to look elsewhere.
I am currently using a GT 210M and I can play most games pretty confortably on low settings, sometimes medium settings. The GT 210M is miles and miles behind the GT 435M.
