GTX 550 ti SLI OR GTX 560 ti?

So, I picked up 2 550 ti's from newegg for $75 each, with the intent of giving them to my brother for his system, however, his motherboard won't support them in SLI. I currently have a GTX 560 ti on an asrock extreme4 w/ a 2500k and 8 gigs of ram and a 750W psu. I've been checking the numbers and it looks like the two 550's will operate as good or better on most games (and gets a much higher score in synthetics), plus it gives me another 1gb of video ram. What do you guys think? Put the 550's in?

  1. Better use the refund money and maybe some extra for another 560Ti ? With the sli 550 you're at a dead ( upgrade ) end.
  2. no, return the 550ti's. and it doesn't give you more Vram, running cards in SLI the vram is mirrored in each card. So you still have 1gb with 2 cards.
  3. I'd agree that switching to the 550ti's wouldn't be a very wise move. Return if at all possible.
  4. Im currently in a very similar situation. I have a 750w PSU but i havent bought a video card yet. neweggs wattage calculator suggests that 2 560's or 560 ti's cannot be handled by th 750w psu. I think its about 30-50watts over. At this point I have the option of getting a 560ti or 2 550ti in SLI. Im aware that buying the 560ti will give me the option of upgrading later to an SLI cofig but that would also cost me a new psu as well. atleast 800Wpsu would be required. So what do you guys think? im looking at specs right now and it seems that the550ti has better clock speeds but has a hindered bandwidth at 192bit compared to the 560's 256bit. Would SLI give the 550 ti's 384bit bandwidth?

    Also with SLI it would seem that the memory is not combined into 2gb. so would the 1gb between cards hinder preformance?
  5. you must have a lot in your system for it to record that with a single 560 Ti. I had a CM gx750 PSU before and with an OC on both CPU and GPU it was able to handle it. But seriously just return the 550Ti s. A single card solution will still be more stable than dual/triple solutions though dual cards can overtake a single card. For resolutions up to 1920x1080 the 1GB would suffice as of now.

    As I'm running SLi'd GTX560Ti's on a 620w PSU I'd have to say that the calculator is wrong.
  7. get the GTX 560 Ti 448~ :D

    Yep me 2! :) You were the one who said it was fine to do it, so I did it! Great performance! Just make sure you have a good psu lol

    What PSU are you using?

    The Antec High Current Gamer 620W
  11. Not to hijack a thread but darn I am now tempted to go for a 560 Ti SLI.
  12. Righteo, just checking for future reference. The OP hasn't responded to this thread for some time so I'm closing it until they contact me as it's being hijacked.
