SLI question?

Is SLI worth it? I was thinking about buying a GTX 660 for now and then buying another one in the summer, but I don't know if it's worth it. I have seen benchmarks showing the boost SLI/Xfire can give, but I've always heard that there are many inconsistencies with performance, drivers, etc. So, just looking for a little feedback as to whether I should try a 660 now and SLI later or just wait for a stronger single card later.

  1. FYI, I saw a GTX 660 for $199 at a local brick and mortar, so I can always return it if the results aren't that great. I am currently using a 6870 with a 3570k.
  2. Have you considered just getting another 6870? 6870's in CrossFire is a decent setup.
  3. I have before, but didn't really consider it because I would have to upgrade my PSU now to do it. Also, I have the 1gb 6870 and I using all of that and then some at 1080p. The 660's are at least 2gb.

    one monitor at 1080p 1GB would be enough. if you were higher res or using eyefinity or surround then you would want more. IMO there just isnt that big of a difference between the 660 and the 6870 to make it worth dumping the 6870 and getting 660 then adding in another 660 later. I'd add another 6870 then in a year or so step into a higher tier card.

  6. I decided to go with a second 6870 and also upgrade my psu. This came out to be the same price as a single 660 and now I can upgrade to a higher single later. This second 6870 will hold me over till summer. Thanks.
