I had the HD 6850 (~150) previously and it was a pretty good card for the price. That card fits roughly in the high middle between the GTX 550 Ti (~$125) and the GTX 560 Ti (~$200). The 560, in gaming terms anyway, is maybe 15% faster than the 6850 and the 550 is about 30% slower, although it can easily vary depending on game and settings. So basically, if I wanted something about the same or just slightly better I'd have to spend around $200. Then I looked at Nvidia's latest card, the GTX 660 Ti. It has between 2 and 3 times the performance depending on settings for $300. For 50% more money I can get much more that 50% the performance, count me in.
