Is the EVGA gtx 660 ti FTW edition available?

If you're in Canada or the US:
660 Ti FTW 1020MHZ 2GB http://ncix.com/products/?sku=75454&vpn=02G-P4-3667&man...
660 Ti FTW+ 1020MHZ 3GB http://ncix.com/products/?sku=75455&vpn=03G-P4-3668&man...
660 Ti FTW LE+ 915MHZ 3GB http://ncix.com/products/?sku=75548&vpn=03G-P4-3666&man...
660 Ti FTW LE 915MHZ 2GB http://ncix.com/products/?sku=75547&vpn=02G-P4-3665&man...

You can also get it straight from evga's site if you're in the US (international shipping is terrible).

doesn't it have a better heatsink, like the gtx 670 ftw?

Are you sure it was a FTW 670 from evga? The only two I've seen are these: http://www.evga.com/products/moreInfo.asp?pn=02G-P4-267... and http://www.evga.com/products/moreInfo.asp?pn=02G-P4-267... both of which use the 'standard' fan and heatsink. The only upgraded (and not water cooled) 600 series card they have that I know about is the 680 SC Signature http://www.evga.com/products/moreInfo.asp?pn=02G-P4-268...
Otherwise the only difference I know about between them is that some of their cards have backplates and some don't, plus they have different cooler stickers for different versions of their cards.

is the 660ti ftw sold out?
