Hey folks , I'm looking to choose between two dell laptops since I get dell products at 15% off. the laptops are the inspiron 15 7000 with a i5-4200u and nvidia gt 750m graphics and the inspiron 15 se with a 3rd gen i7 and amd 7730m graphics. I'm looking for the laptop with the best gaming performance. cheers in advance for any help. the link is for a side by side spec comparison. http://www.dell.com/uk/p/configuration-compare.aspx?returnURL=http%3A%2F%2Fwww.dell.com%2Fuk%2Fp%2Finspiron-15r-se-7520%2Fpd.aspx%3Fc%3Duk%26cs%3Dukdhs1%26l%3Den%26s%3Ddhs%26~ck%3Dmn
