Lower FPS with upgraded system

So, I recently bought basically a new system.
Core i5 750
Gigabyte P55A-UD3
4 GB G Skill Ripjaw Series DDR3 1600 RAM
BFG OC Edition Nvidia GTX 260
Thermaltake TR2 600w PSU
Now, I expected this system to run almost anything I threw at it. I had the CPU overclocked to 3.6ghz but it did absolutely nothing for my FPS in any game, so I turned everything back to it's original specs. I thought that maybe it was just my video card but my friend and I put together a bunch of old spare parts:
Core 2 Duo 2.67Ghz
4 GB DDR2 RAM
Cheap Gigabyte mobo
XFX 8800GT Alpha Dog Edtion
This part is what pissed me off, the spare system was running things more smoothly than my brand new and quite expensive build. I read all sorts of forums and saw that my power supply at the time (Linkworld Generic 630w) was not quite up to par so I bought the one that I have posted and it had absolutely no effect on my FPS. I am at my wit's end and I will be really pissed if my system that I spent all this money on is actually worse than my old one. None of this makes any sense to me and any help with the matter would be greatly appreciated.
Thanks in advance.

More about lower upgraded system
  1. What games ? what resolution ? In game settings etc.

    Mactronix
  2. Just Cause 2 the benchmark test I get 27FPS on avg whereas the scrap computer got 34 using my GTX 260. Settings are all high as they go with everything on except SSAO and Anti-Aliasing at 4x. Res is at 1360x768.
  3. are the cpu temperatures ok? so it's not throttling down because of heat...
    same settings in the drivers, no forced extra AA or anything like that?
    check the clocks to make sure it hasn't somehow downclocked the card, GPU-Z will show ton of info
    and make sure it's running at pcie16X bandwidth
  4. Without knowing a lot more about the game engine and exactly what the differance between the two cards is its difficult to be sure whats going on.
    Things it could be are that the game is more suited,better coded to run on a dual and dosent like Quads. There could be something that the 260 is capable of doing as far as detail settings go or does differantly that means its actually doing more and so is slower.
    Do you have anything like V-sync on that could cause an issue ?

    Its not good to get hung up on just one game either does the result repeate itself when running other games ?

    Mactronix
  5. 3dmark might give some extra info as well...
  6. Yah....I agree
  7. Okay! So here are the 3D mark scores.


    Your system
    3DMark Score
    P11520 3DMarks
    CPU Score
    38168
    Graphics Score
    9345
    Overview
    Operating system Windows 7
    Processor Intel Core i5 Processor I5-750
    Processor clock 2665 MHz
    Graphics card NVIDIA GeForce GTX 260
    Memory 4096 MB

    This was on 3Dmarkvantage. I don't know if that's a good score or what... Also, it is low fps for nearly all games... BFBC2, Bioshock 2 etc.
  8. Sorry but i have to ask, the older system isnt by any chance running XP is it so that you are comparing a DX9 system with a DX10 system ?

    Mactronix
  9. Nope both are running Windows 7...
  10. You didn't perhaps use the HD from the old system in the new system w/ formatting and reinstalling Windoze ?
  11. No they are different hard drives. I also tried flashing my bios to the latest version and that did nothing... I'm really running out of ideas. What I don't understand though is that my video card runs better in the other system and the 8800 gt runs worse in my system vs the old system. That makes me think that it's the motherboard.
