Texture break while gaming, with a possibly CPU-bottleneck

Hi, first of all I'm really appreciated your time spent on reading this.

I 'm having troubles playing games with these spec:
Intel Pentium G2120
8GB RAM
Zotac GTX 650 synergy edition
MSI B75A-G43 gaming Mobo
500W Saga PSU
---
Problem description:
The problem is that almost every games i touch provides horrible graphical glitches, most notably texture breaking, and some of the games eventually crash.
It 's something like this :
62326B347A247B388DC5660CFB8A01028C7BBD8F

Or sometimes it 's just like this :
6C77075D7C397B5AA11CB05F1D2E24DDC1CDC72F

And sometimes (very rarely) everything is smooth.
I got this kind of stuff on not just DotA 2 but in Skyrim / PES 2014 , etc... too
First I think my video card is messing with me, but when i tried it in my buddy 's system, it runs flawlessly :<
To monitor the system while these things happen, I use Task manager and GPU-Z. The result is that I almost got 80-100% load on CPU, but only 40-60% GPU load, both CPU and GPU run pretty cool, no overheating for sure. So this is where I suspect a CPU bottlenecking, but all of my friends keep saying "No way, those two 're pretty fine together" ... But well what do i know ? I need you guys 's help.
---
Some background of my system:
The CPU and Motherboard was actually taken from another system, that one is almost the same as my current one, except it used to run a Zotac GTX 650 Ti Boost, and maybe a different couple of Ram sticks.
What I did when i moved them to the new system was only reset the BIOS setting of the mobo.
DID I miss something important at this part ? I need a solution, or at least an answer of what exactly is wrong :??:
Any help would be appreciated. Thank you !

oops sorry my mistake, mine was FSP Saga 500W so yeah (updated)

Minimum requirement for the GPU was 400W so i picked a 500W, so i dont think it 's somewhat low on power. My buddy 's system has 450W and it 's fine.
The funny thing is when i lower the setting, the glitch seems to be even worse, it happens quicker lol :??:

Ok i 'll go into the details:

the old system was:
+ MSI B75A-G43 gaming
+ Intel pentium G2120
+ ZOTAC GTX 650 Ti Boost
+ 8 GB 1600 RAM
+ 500 Watt Saga PSU

I now make a new system, using those existing mobo and CPU, with the new hardwares below:
+ ZOTAC GTX 650 Synergy Edition
+ 8 GB new couple of RAM stick
+ New 500 Watt PSU
+ New HDD

And I got those problem described. The thing that bugs me the most is - I'm not sure if i missed something or not, when i just used an old Motherboard like that wihtout any modification, not sure if it causes the problems.
 
Download driver sweeper and clean out any and all NVidia drivers on the computer. then download the newest version from NVidia and install them.

I wouldn't think there would be an issue going from a 650 ti to a 650 but lets make sure.


edit: also when using the new Motherboard and cpu did it come with a harddrive with and OS installed or did you just transfer your old harddrive with is OS over to the new board? If you did the second one there may be chipset and driver issues when doing this.

I used a brand new HDD and installed windows 7 64 bit on it myself.
I will try the Driver Sweep tomorrow, i have to go now. Thanks for your assistance, I will report back.

Okay so i tried Driver Sweep to re-install the newest driver, that didn't help though
I tried move the card to another PCI slot, still texture breaking.
This time I really really think the CPU is bottlenecking OR somehow the card is overclocked too much - even i havent got a single thought about overclocking it (a friend told me that when GPU mem clock is overclocked too hard you get this)
So I tried to underclock the GPU, and suprisingly at -150MHz mem clock, all the games run smoothly @@
So is there any explanation ? Can i do anything to avoid underclocking ?
