hi there :) 

i was thinking about getting EVGA GTX 660 SC 2GB

current system
CPU: AMD phenom ii x4 @3.2GHZ ( non-black edition sadly = no OC )
motherboard: ASUS m4a88t-m
PSU: cooler master extreme 500w ( will be replaced with SeaSonic S12II Bronze 520W )
ram: kingston 4GB 1333mhz
GPU: EVGA GTS 450 1GB OC @ 882mhz core
resolution: 1600x900 ( not going to use any higher resolution )
games : infestation, team fortress 2, battlefield 3, nether (alpha) .. nothing too fancy

sadly my processor is not BE so i can't overclock it :(  .. or at least that's what i think, i googled and everyone is just talking about BE so i think i might have to stick with 3.2GHZ which probably gonna cause some serious bottlenecking

if the gap is big (80% or lower GPU usage) i will probably just get a GTX 650 - GTX 650 ti instead .
i really need your opinions

i apologize for my English
thanks in advance :)

No, there will not be a considerable bottleneck. Bottlenecking isn't always a 1:1 thing. What I mean by that is, just because your CPU isn't up to par, doesn't mean you'll get bottlenecking every time you're gaming. Unless you have a terrible CPU, bottlenecks will only occur when the game is particularly CPU-bound, that is, when it is very CPU intensive. So for example, you may encounter bottlenecking for games like Skyrim, Borderlands 2, or Crysis 1. But for games that are not CPU-bound, such as Call of Duty or Crysis 2/3, this bottleneck will either be very limited (to the point of not being noticeable) or, even more likely, will actually not be existent.

By the way, you can overclock. The difference between a Black Edition CPU and a non-Black Edition CPU is that the multiplier is unlocked. If that sounds foreign to you, then you probably never tried overclocking before, but basically, when your CPU multiplier is unlocked, you can just increase your CPU's frequency without affecting other parts. However, in the case of a non-BE CPU, you can still overclock simply by increasing the FSB (Front Side Bus)/BLCK (Base Clock). The advantage to increasing the multiplier is that you can get a stable overclock very quickly. When increasing the FSB/BCLK, you're increasing the base frequency which in turn increases the frequency for all the parts (CPU clock, North bridge, HT Link, RAM, etc). Because of this, you need to then lower the frequencies of these other parts so as to ensure that everything remains stable.

Anyway, get the GTX 660. Hell, even get the GTX 660 Ti if you can afford to. Given what I've told you, you can always overclock later, and the initial bottleneck you have well only be present in certain games, and it shouldn't be that terrible from the start.

i actually tried and noticed that my CPU multiplier is locked so i guess i will start studying and understanding how overclocking works in general in order to Overclock my 955 using the hard way :D  in the near future .

other opinions are more than welcome ^_^
