Key differences to the above posted build,
1) Motherboard/RAM - The RAM has a higher frequency than the Motherboard supports.
2) PSU- This build requires 380'ish Wattage, downgraded to 500W of a more respected brand
FIFA 15 will play with ease on an i5 CPU with an r9 GPU and 8GB RAM plus plenty to spare for multitasking
And yes this build will last you for a long time before you need any upgrades at all
If say 5years down the line you were to upgrade the GPU, you would get much better performance boost getting a whole new GPU of that era, rather than crossfire of the of the same old card x2
All of the above is just for the tower. If you need a monitor, peripherals and OS the build wont definitely be high end.
This quote from above is very true
The GPU has a port for HDMI, DVI, 2x Mini-Display Port, you could connect to a TV with one of those ports if you do not have a monitor for this build already
