What should I replace first

My pc just doesn't have the spunk it use to, I know a lot of the parts are getting pretty aged now. Should I go for a new cpu/mobo or gpu first? I play mostly GTA V, WoW, BF4, NS2 and I also do some light video editing

Current PC Specs:
MOBO: BIOSTAR T5 XE CFX-SLI LGA 1156 Intel P55
CPU: i7-870 2.93GHz 8MBL3Cache LGA1156 95W Quad-Core
RAM: (2) A-DATA 4GB(2x2GB) 240-Pin DDR3 SDRAM 2000G
SSD: OCZ Agility 3 240GB Internal SSD SATA III 6Gbps
PSU: XION XON-1000P14F 1000W SLI/CrossFire
GPU: EVGA 780 ti 3G-P4-2881-KR 3GB GDDR5 PCI-Express 3.0(x16) 7000 MHz 876 MHz
Case: Full size

Both the CPU and GPU will be able to handle apps just fine. They were the beasts of their time in existence and still match thier successors. The GPU is a complete beast and is as good as a gtx 980. The CPU is slightly older, and a lack of IPC AND transistors make it slightly slower, but it will handle okay. But then you have a shitty ram kit. I suggest you to upgrade to at least a 2x4 kit, but I reccomemd a 2x8 kit. Then you have a shitty PSU. Replace it with a good PSU like a EVGA 650w GS or a XFX TS 650. You want to get rid of the PSU first. It is crap and will harm your system. Lastly you might want to upgrade the CPU and mobo. You might consider a used i7 3770/90k np and a mobo for better CPU power.
