Guild Wars 2

Hi this is my first post on the forum and I would appreciate your help.
I have decided to downgrade my tower Pc to a tiny cube Pc. I only really use my Pc for playing guildwars 2. The Pc I am using now has a 7970 Graphics card.
I have been looking at maybe a zotac Magnus EN 980
Specs
Processor Intel Core i5-6400 (quad-core 2.7GHz, up to 3.3GHz)
ChipsetIntel, NVIDIA
System Memory 8GB DDR3L SODIMM
Graphics
Graphics Engine NVIDIA GeForce® GTX 980 w/ 4GB GDDR5
Video Output 2 x DisplayPort 1.2,
2 x HDMI 2.0

Or maybe a GIGABYTE BRIX
Specs
Features latest Intel® 4th generation Core™ processors – i7-4710HQ
Supports discrete graphic card (NVIDIA GeForce GTX 760 GPU with mini HDMI x2, mini DP Output, featuring triple displays)
Supports 2.5” Hard Drives (1 × 6Gbps SATA 3)
Ultra compact PC design – 0.88L (59.6 × 128 × 115.4 mm)
1 x mSATA SSD Slot
2 x SO-DIMM DDR3L Slots (1333 / 1600 MHz)
IEEE 802.11 a/b/g/n/ac Wi-Fi / Bluetooth 4.0 Mini-PCIe card
4 x USB 3.0
Gigabit LAN

Would either of the above run Guildwars 2 without any problems? Any alternatives/suggestions would be appreciated.
