5670 & 5750

Im looking at upgrading my gpu as i have a 9400gt which really just isnt quite there ay. Im looking for something that could do directcompute as my cpu doesnt do physics properly, as its a 3ghz P4HT. upgrading my cpu isnt an option, so i want a card that would be powerful enough to do directcompute but also run on my dell 350w dual 18A psu, so i narrowed it down to a 5670 or 5750. The 5670 would work, but im not sure about the 5750. Another thing is would dieectcompute work on a pcie 1.1 x16 port? I would consider an nvidia, but in NZ theyre WAY overpriced

More about 5670 5750
  1. before i answer, you should post wut ur monitor resolution is so we can further answer your question. the 5750 is better by a bit but also costs $30~ more then the 5670, the performance is not very noticable but if u can save up a lil bit more get the 5770 it is worth it

    hehe, ive got a 17" 1280x1024 lcd. im more worried about what my psu could cope with atm, coz id just get the best it could handle
  3. If you are sure the Dell PSU outputs true power, then you can use this calculator to check if your PSU will support more than the 5670 or 5750.

    I think it can support the 5750 but the next question is does your PSU have the PCIe 6PIN connector it needs?
  4. i recommend upgrading ur psu cuz i dont know if its one of those cheap psus that say they run 350w but only run 250~300w, its only an additional 50~100$ depending on wut u choose, i prefer 500~750w
  5. From what ive heard, the opposite is true, it supposedly outputs 400-450w. Yes, it also does have a 6pin

    I've heard similar, that dell for some reason underrate their psu's, well i guess maybe so you just buy a new system, but you probably want to look the output sticker and calculate it yourself, then go to one of those psu calculators, i'm pretty sure the 5750 uses less then 100watts. so their still a chance now that you know you have a 6 pin connector
  7. Dell PSUs are more powerful than rated on the sticker. However, I would say the PSUs are more like 40w - 50w at most.

    The HD 5750 consumes about 58w of power under typical gaming conditions.
  8. Yeah, that PSU can handle an HD5750.
    In terms of gaming performance the HD5750 is about 30-40% more powerful, depending on your resolution. Which you should buy is your call.
  9. thanks for all the replies but also whats your opinions on directcompute? would it help compensate for my cpu, or is it just gonna be a waste?
  10. I would think it will work fine as long as the software you are using can use it.
  11. I would agree most likely it'll be quite awhile before it really starts showing up. But once it gains some traction it should be pretty predominate since both ati and nvidia support
  12. cool ty guys. ill pick up a 5670 as soon as i get the money
