Is my GPU failing or is my outdated CPU holding my GPU back? GTX650/Intel Pentium E5300 dual core 2.60GHz

Back-Story

I have been a console gamer all my life, I made the transition to PC gaming about 18 months ago.

I quickly learned that my 9 year old PC couldn't handle most modern games and much slightly older games like TF2.

I figured it was due to my graphics card being severely outdated.

I purchased a brand new NVIDIA GeForce GTX 650 card from new egg around 6+ months ago.

Once installed, I noticed little to no difference in my frames per second in games. Being very dis-appointed I was about to return the card before I learned my outdated CPU may be limiting my Graphics cards performance. (Intel Pentium E5300 dual core 2.60GHz)

I have recently saved enough cash to purchase a CPU that wouldn't be much faster but give my games more breathing room to operate.

Actual Problem

Today I was playing on of my favorite games and whole textures would flash black and white with some just dis-appearing entirely allowing me to see through the 3D world. The skybox flashed rapidly attempting to give me a fit of epilepsy. This could just be an in-game bug, but it seemed un-likely.

This quickly made the game un-playable and hinted that perhaps it was not my CPU with the problem, but my graphics card being made in the factory with a problem which I understand is fairly common.

I think its too late to return the card if it is faulty I don't have enough cash to drop 100's of dollars on new parts every month.

Bottom line is I wanna know if I need to buy a new/return my GPU or continue to go along my original plan and upgrade my CPU.

Any responses will be greatly appreciated.

You need to overclock on a massive scale to see improvement.

You should really aiming for about 4Ghz but really any amount will help.

This is completely related to the CPU so not to worry the graphics card is fine.

EDIT Actually yeah that sounds like a heat issue my bad.

If you have a friend or acquaintance that has a reasonable computer, you could connect the videocard to it and see if the problem persists. Also regardless of the return policy you have 2 years warranty at least from nvidia them selves and they will repair or if need be replace the card.

It is entirely possible a dual core is limiting you severely during gameplay. My advice is to test the card in a different setting like a friend's computer or a computer repair store they often have test benches for that sort of thing. Sure you will drop like 10 ponds for it or free if it's a reputable store. But you will have your answer. Could also be different reason outside of the CPU GPU conundrum you find your self in.

Also the CPU is most certainly a bottleneck for your card.

Thank you all for your detailed responses. I have another question: What sort of CPU should I be looking to buy and how much would it cost? My budget is around 150$

Your actual problem sounds a lot like artifacting.... what sort of case/ventilation do you have. What PSU are you using? The CPU will not produce the problems with textures, overheating GDDR will. How much space is around you card for airflow? Also pls could you get a program like GPU tool to monitor the GPU temperature sensors (all of them not just the GPU)

My case ventilation is very poor because I have a busted case fan which is temporarily being replaced with a large fan blowing into an open case.

From what I remember my temperatures are pretty high while the exact numbers escape me at this time.

My PSU is 600w.

Thanks for the response.

Than perhaps that's where you should start. Fixing the ventilation problems and benching to see what temps you are running. Download GPU-Z to see the graphic card temp. And use CPU-Z or Everest or any other temp suite to check your CPU during load.

GPU temp - 36-42 degrees Celsius

CPU temp - 42-45 degrees Celcius

Well than it's not heat issue what you are experiencing. Also is the 42-45 degree graphic card during GAMEPLAY or is it without you doing anything. Cause man if that's your gaming temp you have my thumbs up. I have 45 with watercooling on during gameplay. Most likely something else is the issue.
