Who is using GTX660?

I'm using Gtx 690.

I'm using that same exact card (Picked it up for $150 at Best Buy new last month) :D

As for performance, I'm maxing out every game that I have played so far (Black Ops 2, Saint's Row 3, Assassin's Creed: Brotherhood) at 60FPS with a 1920x1080p, so it's definitely good. Also it seems to get around 40FPS with the same settings for Battlefield 3. Runs well on my 500w, even though it's cutting it close. Must say that I'm loving it.

Got gtx460 too! And actually I'm wondering the same thing, gtx 660/gtx 650ti boost or wait for series 7

GTX660 is a noticeable jump up from a 460, I think it was around 25-30% if I remember correctly.

Edit- actually its better than that, its 25-30% better than the GTX560ti

Comparison of the two

I can attest to EVGA's (as well as Nvidia's 600 series) performance and customer service. I rock an EVGA Geforce GTX 680 4GB Classified and it has yet to fail me. It may be a bit overkill but it's my baby.

I went from a 460, to a 560TI, to my 670. Biggest performance boost was from the memory increase.

the 660 is what I'm thinking I'm going to upgrade to(currently running 9800gt 512mb). It is roughly the same dimensions as my current card and should work with my current power supply(I really would prefer to avoid changing out the power supply as well if possible). I'm mostly just waiting on my tax money to come back and a game on my radar that warrants the upgrade.

That's the exact card I have and I've had no problems running most games on maximum settings. Not technical enough to offer much more than that though, sorry!

I have a MSI GTX 660. It runs everything on max fine, but my monitor's max resolution is only 1280x1080.

I have an EVGA 670 FTW which is a 680 minus some stream processors, and I think the memory clock is higher than the 680
My PC is a beast =) I had some weird problem with Intel Rapid Storage drivers though and had to reinstall Windows...

GTX560's not dead.

I have a Palit GTX 660 2GB and i'm satisfied with it's overall performance, but it was expensive for me.
