Hi everyone,

Is it better to run 2 video cards on a mobo which offers x8/x8 in sli or a single card on the samo mobo which offers x16 at one slot. In other words, this mobo offers x8/x8 OR x16

Motherboard in question:

Card would be gtx 260 ... possibly gtx 470

Thanks!

If the cards are equal, it will be better running two cards in SLI at x8,x8 versus one card at x16.

Now, if you are running say a SLI GTX260 or a single GTX470, the single GTX470 would be the route to go, so you have room to upgrade to SLI down the road. You might have some initial FPS lost (still very much playable) but once you add another GTX470 down the road, your performance would be much much better!

yes the question was indeed in reference to running the identical cards in SLI or Singly:

ONE gtx 260 at x16 or 2 gtx 260's at x8/x8


OR


ONE GTX 470 at x16 or 2 gtx 470's at x8/x8



I have the MOBO, and i am trying to decide whether to go SLI at x8/x8 or Single at x16 with ANY card.

Thank you tecmo34 ... so SLI at x8/x8 for ANY card is always better than ANY single card at x16? Just comfirming.

And you're saying that a single gtx 470 at x16 does not perform as well as 2 gtx 260's in SLI at x8/x8??

Thanks! :hello:

You are correct... SLI at x8/x8 for ANY card is always better than ANY single same card at x16 (you may find some older games that don't scale as well in SLI, so it isn't 100% of the time better).

However, I would recommend running just one GTX 470 and upgrade down the road to a second card, once performance decreases. When you are running an SLI setup from the start, it leaves you no upgrade path outside of purchasing new card(s)... IMO

Your best option is to PM a Moderator (Randomizer or 4ryan6 come to mind, which who I dealt with most for things) and request them to select which ever post you want as the best answer. You can PM a Moderator by clicking on their name on the main forum page and hit send private message.
