Buying a GTX680, will the rest of my system be a bottleneck?

Hi

I am considering the purchase of a "Gigabyte GTX680 SOC 2gb" video card http://www.netplus.com.au/product/VDGIGTX680-08/Gigabyte_GTX680_SOC_2Gb_D5_GV-N680SO-2GD_Super_OC_nVidia_Kepler_680 but I am starting to wonder whether the rest of my system's components should be upgraded first. I am thinking that they may be too much of a performance bottleneck to warrant the purchase of the new card.

The current specs are:
  • i5 760 overclocked to 3.4 ghz
  • 8gb DDR3 1333 MHz RAM, probably will buy some 2133 MHz when I get the card
  • 750W TP-750 Antec PSU
  • GA-P55-USB3 motherboard, with two x16 GPU slots (one operates at x4 when in crossfire/sli though)
  • HAF-X case


    I am sort of asking two things.

    Firstly, will my PSU even provide enough current to run the card? The card requires "a minimum 12V current rating of 38A" yet I cannot find the current that my PSU can supply. It does however have "4 +12V output circuits", whatever that means. Where can I find the maximum current that it supplies?

    Secondly, assuming my PSU is up to the task, will the rest of my system be too much of a bottleneck to even benefit from a faster graphics card? I currently have an HD6870 and will buying a faster card be that much noticeable with the system that I currently have? Or should I spend the money on upgrading the rest of the system first?

    Thanks for any help,
    James

    Thanks, but do you know any definite way to find the maximum current that the PSU can supply?

    Yes, I found the sticker:

    (Let's hope this ASCII table works correctly:) 

    DC OUTPUT | +5V | +3.3V | +12(1)V | +12(2)V | +12(3)V | +12(4)V | -12V | +5VSB |
    MAX (A) | 25 | 25 | 25 | 25 | 25 | 25 | 0.8 | 3 |
    MIN (A) | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |

    just a quick note on that graphics cards you are interested in, unless you plan on picking up the card from netplus, have you considered buying from pccasegear? the card is $20 cheaper and postage prices seem about the same.

    Haha BigMack70 - that is the sticker that my ASCII table was trying to copy...

    And yes, shadyhamster, netplus is very close to my house so i was thinking that i would just pick it up from there. Thanks anyway.

    Anyway, now that I know I have 62A, and that the PSU should be enough, does the rest of the system seem fine (other than the CPU sometimes stopping it, thanks BigMack70)?

    if you are close enough for pickup to be an option then that is the best way to, will make dealing with rma's alot easier if it ever needs to be done.

    as for your other concern, IMO your system is perfectly fine, maybe upgrade at a later date if you want the few extra fps gain from a cpu upgrade but im sure after you plug in that 680 you will be more then happy with the results.

  • HAF-X case




  • your power supply is just fine and so if your cpu.i5 760 is old but still a capable cpu,just give it a good overclock(3.8-4GHz).8GB 1333 MHz ram is good enough,2133 MHz will not show any magical improvement.
    go ahead.
