GPU should run on HIGH settings,but lags except when on LOW. Why does Benchmark software shows low 3D Frames Per Second (fps)?

Hello friends!

My Dilemma :( :

I have two low budget new PC builds that are fairly similar. PC #1 runs games such as League of Legends and World of Warcraft on "High" settings with no lag. PC #2 lags when using the same settings as PC #1 despite using a slightly better version of the same graphics card.

I've checked both PCs to mirror all settings using the Catalyst Control Center and in-game settings. I don't know what is causing one graphics card to under-perform. These are the only home builds I've done, so my experience is limited and so was my budget... So, please don't make me feel bad about not spending more money on higher quality parts. As I said, PC #1 works great for me, "high" (not ultra) settings with no lag. Also, I have dusted inside of both PCs with compressed air. No noticeable change in performance, but it was quite dusty.

Any ideas on what would be causing PC #2's graphics to under-perform? Thank you kindly for reading! :love:

I used a free benchmark program (https://novabench.com/) on both computers:

Why does PC #1 have double the score of PC #2 on the graphics tests? They should be almost equal.

  1. Best answer
    The HD 5700 is stronger than the HD 6570, plain and simple.

    720-800 VLIW5 stream processors, 36-40 SMUs and 16 ROPs versus 480 VLIW5 stream processors, 24 SMUs, and 8 ROPs.
  2. even 2 6570 would not match a 5770 / 5750
  3. Okay, here's what happened. Back in 2011 when building my PC, I had originally ordered this graphics card (http://www.newegg.com/Product/Product.aspx?Item=N82E16814102874). Before I even received it, I decided to go with this card (http://www.newegg.com/Product/Product.aspx?Item=N82E16814102898). So, I ended up installing and using only the second card because it was better than the first one. I gave the other one to a friend, but I must have got the names mixed up back then.

    I thought I was running on http://www.newegg.com/Product/Product.aspx?Item=N82E16814102874, when really
    I have this one installed http://www.newegg.com/Product/Product.aspx?Item=N82E16814102898 (and its twice as powerful as the one above).

    I mixed up the cards and that's why I didn't think there should've been such a gap in performance.
  4. Just FYI,

    I upgraded that weak card (http://www.newegg.com/Product/Product.aspx?Item=N82E16814102994) to this one:
    GeForce GTX 750 Ti (http://www.newegg.com/Product/Product.aspx?Item=N82E16814125502) for $149.99-$30.00 rebate.
    I can run World of Warcraft on ultra settings with no lag, and its lovely!

    I ran into one problem while trying to install the software for the graphics card. The setup.exe file kept freezing and under task manager said it was "Not Responding." I tried booting from the disc, and uninstalling the AMD Catalyst Control Center that was currently installed on the PC.

    The solution I came up with was downloading the software directly from the company's website http://www.geforce.com/drivers/results/80913. No more bumps after that!
