New Graphics Card - GTX 660 non Ti or 7850/7870

[Timon83]

Hi Guys,

owning the game since the beginning, playing occasionally with a machine "fired" by an ATI 4850, I'm thinking about really getting into COD.
So I'm thinking about getting an GTX 660 or a 7850 / 7870 with 2 GB vRam.

I read, that the GTX 660 can not access ram at full speed if the ram is filled with more than 1,5 GB. I wonder how the impact on performance is. Does anybody have any experience with the GTX 660?

I prefer a quite and cool system. Therefore overclocking is not really an option. The new graphics card should be silent or barely hearable.
Also I don't want to spend more than 230 Eur. I know that my CPU is a bottleneck for any better graphics cards and I'm not planning on upgrading my CPU. I don't have to have everything on max.

Priorities:
- silent
- cool
- COD performance / compatibility
- price

These are my specs:

Q8200 native QuadCore @stock
4 GB Ram
24" TFT @1920x1200
80 GB Intel SSD
