Which one of these laptops is better?

[GodOfWaffles]

I am able to get one of these laptops for a cheap price(~610EUR). I plan on using it for some moderate gaming(DOTA2, CS:GO, Civ5) and as a general purpose laptop, so which one is better?

DELL INSPIRON 5737
Processor: Intel® Core™ i7-4500U Processor (4 MB Cache, 1.8 GHz)
RAM: 8gb DDR3 1600MHZ
HDD: 1TB 5400rpm
Graphics Card: Radeon HD 8870M 2GB GDDR5

DELL INSPIRON 5748
Processor: Intel® Core™ i7-4510U Processor (4 MB Cache, 2.0 GHz)
RAM: 8gb DDR3 1600MHZ
HDD: 1TB 5400rpm
Graphics Card: GeForce GT 840M 2GB GDDR3

The Radeon based system has the better video performance (by about 25%), but the speed of the CPU is the slowest of all of the i7 systems. Ideally you would get a faster i7 or even i5 on that computer.

That is a good price, however

The DELL INSPIRON 5737 is better. If the nVidia GT 840m used DDR5 RAM instead of DDR3 RAM, then perhaps the performance would be somewhat similar.

The difference between the Core i7-4500u and Core i7-4510u is only 200MHz at the base speed. However, with Turbo Boost they operate at 3.0GHz and 3.1GHz respectively; only 100MHz difference. The difference in CPU performance is very slight compared the GPU performance.
