No difference between GTX 560 SLI vs 8800 GTS 512 SLI

Yesterday I upgraded my computer, but I didn't get any difference on benchmarks...

With 8800 GTS SLI on Crysis with (Crysis bench tool) : 28,5 average.
With GTX 560 SLI, same benchmark tool on Crysis : 35 average.
On single GTX 560 mode : 30 average.

I know that maybe there's bottleneck on the motherboard. There must be something wrong, but I don't know what is it.

My computer specs are :

CPU : Intel Core 2 Duo E6850 ( 3ghz )
Motherboard : Asus Striker II NSE
RAM : G.Skill Ripjaws PC3-16000 4GB
PSU : TACENS RADIX V 850W

Would appreciate any suggestions, thanks.

  1. Probably your CPU is the limitation.
  2. Yep. I doubt that your C2D would be able to max. one gtx560, let alone two.
  3. of course your cpu is pretty older and you are running two gfx card with it yes a big bottleneck occurs.
  4. Thanks, so worth spending € 400 on a new motherboard and a i5 2500K?
  5. Three correct answers in a row, who'd have thunk it? :lol:

    @OP, OC the crap out of your CPU.

    Yes. Your frames will improve massivley on every game.
  8. I'm using lasted drivers on nvidia.com. I thinking of full refund from graphic cards and wait until Ivy Bridge and 6XX..
  9. GTX 560 non-Ti. Nice idea selling what I have but don't spect too much luck.

    Let me correct your sentence to better OP understandment.

    Your frames will improve MASSIVE GREAT SUPER on every game.
  11. The 5XX series have more than one year, I don't think it takes much until series 6XX comes out.

    I must use the 750€ on the best way possible.

    Thanks again
  12. you cpu is bottelnecking gtx560 sli .... buy an mid range cpu like i5 or i3
  13. You can try to push your c2d but you won't get much out of it maybe up to 5%. You can get AMD Phenom II X2 565 black edition and unlock all cores to get full X4 plus overclock close to 4Ghz that should give you like more juice than c2d. Also get some cheap mb like BIOSTAR TA990FXE . This upgrade should cost you about $220~€170
    Good luck

    OC'ing the existing CPU would be cheaper, less hassle and probably give better returns.
