Which one of these two should i buy?



That depends on the exact card, but all things being equal, the GDDR5 card even with less memory should be faster. GDDR5 memory is used in higher end cards.
 
All others specs (except graphic card 2 gb 940mx gddr5 on dell and 4 gb 940mx ddr3 on lenovo ) are same but dell has aluminium body. Dell is charging 155 dollars (10,000 rupees) more for this graphic card and aluminium body, is it worth it??
