I've been keeping my eyes on the upcoming 660Ti as I currently don't own a discrete video card. But comments from various sites have shown that the specifications will be exactly the same as a gtx 670 except the 660Ti will use a 192-bit bus than a 256-bit one. I've also seen a lot of comments where people are saying this will "cripple the card's performance by a lot" but then I've seen others say it shouldn't matter if you're using just one monitor to play your games as the memory bandwidth only comes into play at high resolutions (2560x1600 or whatever and up) or when using multiple monitors.
So I'm just wondering if using a 23-inch monitor at 1920x1080 resolution, will the lower memory bandwidth have much effect, if any, at all? I know a lot of gamers on those PC sites tend to have, in my opinion, "high standards" but I'd just like to know the drop in performance objectively (as in any FPS drops/rendering/etc) as I don't really know much at all when it comes to actual performance.
Also yes I know it's not out yet but I'm sure it's possible for someone to know if all other factors are kept the same, excluding the memory bandwidth, what that entails. Any help would be greatly appreciated.
