will this build work

[13 year old trying to build a pc]

So i just finish choosing parts for my PC build.This are the parts:
Intel Core i5-4690 Processor (6M Cache, up to 3.90 GHz, LGA1150)
Asus H81-GAMER Motherboard (ATX, Intel H81, Socket 1150)
WD Caviar Blue WD10EZEX Hard Drive 1TB
Asus STRIX-GTX970-DC2OC-4GD5 Graphic Card (NVIDIA, 4GB GDDR5, PCI-E 3.0, 256-bit)
Kingston HyperX DDR3-1600 1.5V 8GB (2 x 4GB) Desktop RAM
Cooler Master Elite 431 Plus Mid Tower Chassis
Corsair VS Series VS550 Power Supply

so i have a few questions:
1.will this pc be able to game with 3 monitors 1080p (games:league of legends,
world of warcraft , minecraft,flight simulator x, titanfall , battlefield ,GTA5)
2.can i change and parts that have the same performance but are cheaper.
3.know any monitor with dvi and hdmi ports?

thanks!!!
