Hearty Greetings to you all Gentlemen! I’ve bought the computer & here’s the system:
GPU: NVIDIA GeForce 660 GTX 2 GB
Processor: Intel core i5
OS Architecture: 64-bit
Memory: 8 GB
OS: Microsoft Windows 8(or 8.1, I’m not sure, I’ve not unboxed it yet because the graphics card will be delivered & installed today by the store service)
Computer Type: Desktop
Will UDK & UE4 BOTH work on this computer? Thank You All Very Much! 
Cheers! For Epic Games & All Of You!
