Can this build run newer games at ultra/high settings @1080p
I'm not really looking to overclock at the moment also this is my first time custom building

Case: Aerocool X-Predator Case Devil Red Edition
GPU: Asus gtx 770 DirectCU ll oc 2gb
CPU: i-5 4670k
MOBO: MSI B85-G43 Gaming Motherboard
SSD: Samsung 840 EVO 120gb
HDD: Seagate Barracuda 1TB
RAM: Cosair Vengeance Pro 2x4gb
PSU: Antec High Current Gamer 620W Power Supply HCG-620
OS: Windows 8.1 64bit
Fans: 2xCorsair Air Series AF140 Quiet Edition High Airflow 140mm Fans

Now I'm not to sure about changing the stock fan/heatsink on the CPU since I'm not really looking at OC'ing I just got the extra 2 fans for the bottom and rear of the case since they are not included I also went with 2x4gb ram since I've heard all you really need for gaming is 8gb ram is there anything else I should think about adding or changing?
