I am going to get a MSI GT70 and I was wondering if you make the CPU from the
i7-4800MQ to the i7-4700MQ(getting it from XoticPc.com so they can take off $109 to downgrade it) would it effect the GPU's performance?

SPECS(before downgrade):
•Windows 8.1
•Intel® Core™ i7-4800MQ Processor(3.7-3.4GHz)
•17.3" Full HD Anti-Reflective Display (1920x1080; 16:9)
•NVIDIA® GeForce® GTX 870M 3G GDDR5
•Matrix Multi-Monitor Display Support
•Efficient Single Fan Thermal Cooling with Cooler Boost 2
•Full Color Programmable Backlit Keyboard by SteelSeries
•1TB HDD (7200RPM)
•8GB DDR3L 1600MHz System Memory
•Killer™ DoubleShot Technology (Killer™ E2200 + Killer™ Wireless-N 1202)
•USB 3.0 x 3, USB 2.0 x 2
•VGA, HDMI, mDP
•DVD Super Multi
•Built-in 720p HD Webcam
•World-Class Dynaudio Premium Speakers
•Audio Boost Technology

Thank you for looking at this post.
For moderators: I posted a subject about a MSI Laptop, but not about the same laptop and this time I need to know about a performance change if I downgraded the CPU.
