Need HELP, good build - low FPS

[Verard]

Hello community, as the title says I have a decent build and I play with around 15-20 FPS, more info below, also note that I will post 2 builds, the first one is my friends' and he plays with 100+ FPS(on a worse build) and the 2nd one is mine and I play with 10-30(Keep in mind we mostly play MMORPGs, WoW/Tera/BnS etc etc)

So I will post a speccy scan of my friend's to give you an idea:

Operating System
Windows 7 Home Premium 64-bit SP1
CPU
Intel Core i3 2120 @ 3.30GHz 51 °C
Sandy Bridge 32nm Technology
RAM
4.00GB Dual-Channel DDR3 @ 532MHz (7-7-7-20)
Motherboard
ASRock H61iCafe (CPUSocket) 38 °C
Graphics
22M35 (1920x1080@60Hz)
1023MB NVIDIA GeForce GTX 550 Ti (CardExpert Technology) 63 °C
Storage
931GB Hitachi HDS721010CLA332 ATA Device (SATA) 40 °C
Optical Drives
ELBY CLONEDRIVE SCSI CdRom Device
HL-DT-ST DVDRAM GH22NS70 ATA Device
Audio
Realtek High Definition Audio

and 550V power supply

The above PC runs wow and pretty much all MMOs on 4/10 graphics with 100+ fps and 30+ on ultra.

And my PC specs are:

Operating System
Windows 7 Home Premium 64-bit SP1
CPU
Intel Core i3 4160 @ 3.60GHz 59 °C Haswell 22nm Technology
RAM
8,00GB Dual-Channel DDR3 @ 798MHz (11-11-11-28)
Motherboard
ECS H81H3-M3 (SOCKET 0) 28 °C
Graphics
HDMI (1920x1080@60Hz) 4095MB NVIDIA GeForce GT 730 (MSI) 64 °C
Storage
111GB TS120GSSD220S ATA Device (SSD) 25 °C
Optical Drives
ATAPI iHAS124 E ATA Device
Audio
Realtek High Definition Audio
and 400V power supply

And the above build runs the same games on significantly lower FPS as mentioned above, we even called a PC Tech to check it out and he didn't know WTF is wrong he recommended swapping out each and every part(graphics card -> motherboard->power supply) until we find out what causes the low FPS but we don't have the money to do it so I'm posting here hoping someone can help.
He also formatted the PC and changed the hard drive to an SSD but it didn't make any difference.

If you want any other info about my PC please let me know and I will post it asap, I'll be checking the thread regularly.
Thanks in advance and all the best

The GTX 550ti is faster than a GT 730. Also there are multiple versions of GT 730, so if yours isn't the better 64bit, GDDR5 model, that performance gap is even higher. Pretty sure yours is the slower ddr3 equipped model. Also that is not volts, but wattage, for the power supply.
