I wanna upgrade my graphics card and im scared that my CPU will bottleneck it. Specs are:

CPU: Intel Core 2 Quad Q8300 2.5GHz
Mobo: ASUS P5G41CM-LX
GPU: Nvidia GT 240 512MB
RAM: Corsair 4GB DDR3 1333Mhz
SSD: Samsung 830 128GB
HDD:Samsung Spinpoint F3 1TB
PSU: Corsair AX750W(will be when i get a graphics card upgrade
OS: Windows 7 Ultimae 64-bit

So will my CPU or any of my specs bottleneck a ASUS GTX 670?

Yes but it should be fine for now if you are upgrading later. You would want a core 2 quad in the range of 3.2 to 3.4 ghz to really get everything and even that might not max out the 670.

Will there be more than 50% drop in performance because of one plain factor, CPU is bad?

I'm guessing here based on older charts, because there are none comparing your CPU to a modern one but at a guess I would estimate you could loose between 25 and 33% performance due to the CPU.
2.5GHz is very slow by today's standards. These CPU's came out when the Quad is better because games will all be using more cores brigade were shouting it from the rooftops.
Sadly for you that has not been true. Today its starting to become a reality but the 2.5GHz your CPU has is too slow.

The thing is will it give playable and enjoyable frame rates ? It is nearly 4 years old now.

Are you saying that it will definately not give a playable frame rate then?
What fps do you think it will be able to maintain on ultra settings in BF3 with a 60hz monitor, baring in mind that it will be paired up with a GTX 670 with Vsync most probably on?

No I'm not saying it defiantly wont be playable.
What resolution are we talking about playing at ?
1920 X 1080 would be best as the higher resolutions put the burden on the GPU more than the CPU.

Realistically speaking a GTX 670 is a waste of money with that CPU. I don't know what your prices are like but here in the UK your talking around the £300 mark. While something like a 7850 is around £160. Even going in the middle a 660 Ti would be about £210

You could most probably run the game fine with your Q8300 and a 670 but I would be there would be zero performance difference between the 660Ti and the 670 with your Q8300.

So what's the plan for upgrading the rest of the system ?

If your looking for one last upgrade for what you have then I would go for a 7850 and save the rest towards a new system.
the difference between that and your GT 240 will be huge and you wont have as much of a restriction issue as you will with a 670. It will still be restricted a bit but its way cheaper.

Im in the UK too and im looking at the ASUS GTX670(not top)
And yes the resolution is 1920x1080.

I will be and eventually upgrading the whole of system really, specially the cpu+mobo and ram but im just asking this question because it might not be till the first few months of 2013 that ill be able to buy and upgrade them.

Also what do you think of upgrading to a lower gfx card like 7850 for the moment and then when it gets to like jan-feb get the 670, upgraded cpu+mobo and ram?-or would it just be better to stick with the 670?

Myself personally I would get a 7850 now and upgrade everything later on.

You can sell the 7850 on if you wish or keep it as a spare.

Also the 670 may be cheaper by next year as well.
