I want to buy a laptop with nvidia gt555m, gt630m or gt635m. My budget is nearly up to Rs.50,000.(gt555 may be out of reach). Intel i series is preferred. Processor should be sufficient to play modern games and for 3d designing. 15.4" screen and keyboard with numpad preferred.Please advice laptops with good screen quality(no need for the best but i have heard negative about a few acer laptops). HDD should be above or equal to 500GB. Basically I want the best laptop under Rs.50,000.
