Benchmarks seem to favor AMD and I would like to save the $100, but I am hesitant to try a non-nvidia card. As well, I heard that the Kepler chips were supposed to be the cat's backside. Could also go 660ti with 2gb for $300.
the 660ti with 3GB actually benchmarks less fps than the 2GB version because its 192 bit interface creates a sort of latency between the card and the data. Think of it like this, it's like a sports car that can't utilize all of it's horse power because it's wheels are too small. On the other hand, the HD 7950 3GB has a 384 bit interface which means it can access all the data/shaders/cores literally twice as fast as the 660ti which is why the HD7950 is one of the best cards for the money that's currently on the market. Hope that helps, I wouldn't recommend the 660ti but if you're hell bent on getting it save yourself a little money and get the 2GB version because it really does get 3-5 fps better on almost every game compared to the 3GB version
7950 gets my vote ! Why?Keep in mind this is over a month old review and amd has lower price allot Quote: "As it stands, AMD’s position correctly reflects their performance; the GTX 660 Ti is a solid and relatively consistent 10-15% faster than the 7870, while the 7950 is anywhere between a bit faster to a bit slower depending on what benchmarks you favor. Of course when talking about the 7950 the “anything but equal” maxim still applies here, if not more so than with the GTX 670. The GTX 660 Ti is anywhere 50% ahead of the 7950 and 25% behind it, and everywhere in between. Coupled with the tight pricing between all of these cards, this makes it very hard to make any kind of meaningful recommendation here for potential buyers. Compared to the 7870 the GTX 660 Ti is a solid buy if you can spare the extra $20, though it’s not going to be a massive difference. The performance difference is going to be just enough that AMD is going to need to trim prices a bit more to secure the 7870’s position.
On the other hand due to the constant flip-flopping of the GTX 660 Ti and 7950 on our benchmarks there is no sure-fire recommendation to hand down there. If we had to pick something, on a pure performance-per-dollar basis the 7950 looks good both now and in the future; in particular we suspect it’s going to weather newer games better than the GTX 660 Ti and its relatively narrow memory bus. But the moment efficiency and power consumption start being important the GTX 660 Ti is unrivaled, and this is a position that is only going to improve in the future when 7950B cards start replacing 7950 cards. For reasons like that there are a couple of niches one card or another serves particularly well, such as overclocking with the 7950, but ultimately unless you have a specific need either card will serve you well enough." http://www.anandtech.com/show/6159/the-geforce-gtx-660-...
Thanks everyone. I discarded the 660ti from consideration, leaving the gtx 670 and 7950
At the end of the day, I chose to go with two 7950's. The reason: I saw a lot of debate about which was better the gtx 670 and 7950 - although it seemed to be the "better" card might be the gtx 670 - it seemed close. So I decided to save $160 ($80 per card) and go with the 7950.
