i m using a intel core 2 duo e7400 cpu .i got a e8400 core 2 duo>will e8400 cpu increase the performance??will it increase fps in game??

The E8400 is only 200MHz higher than the E7400 but has double the cache. In terms of mutitasking you will see a slight benefit but if you're looking at FPS increments in games, then the question is, what games are we talking about? On top of that question, performance on the Core 2 platform came from the board, the ram and the processor.

The overall performance gain comes from them which leads me to as, what is your full system's specs?

cpu - intel core 2 duo e7400
ram - 4gb
gpu - radeon hd 6770

games like ac3,battlefield 3,cod blackops 2 etc

e8400 has more system buss speed-1333 MHz,has 6 mb cache which is 3 mb more thn e7400 and more clock speed-3 Ghz> will these extra specification increase the performance or any chance of increasing fps in game?


 
GTX750TI will do a lot for that system. Stock the 8400 is better, but the 7400 can use a BSEL pinmod from 266fsb to 333 fsb for a hefty O/C. The extra cache is worth about 3%.
The O/C should get 3.5GHz.
With a 2GB GPU even with a 32 bit OS you could use more memory. With 2 slots 8GB is the only next step.
Max CPU is Q9650 (Q9550 is cheaper).

When passing your full system's specs, list them like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
Chassis:
PSU:
OS:
Monitor(and it's resolution):
^ Being as specific as possible.

Simple answer, the performance boost will not be by much, minuscule if anything. I played on BF3 with an Intel Q9550 with a mild overclock+HD6870 with also a mid range overclock and I achieved playable frame rates at 1080p with high settings. We're dealing with two Dual Core processors here with a slight bump in frequency and cache. If you got something like a a Q6600 or a Q9550 then that would be a significant upgrade from what you currently have.

Contrary to what has been said, you can't overclock on that Intel board since it's got safeguards implemented within the BIOS. I don't recommend software based overclocked or using setFSB for tampering with the clocks. The board also lacks the proper heatsinks over it's power delivery area to maintain an overclock (if you somehow managed it). On that note, Intel boards are notorious for being picky with what ram/ram kits you drop into the board. So in this regard, buy a kit and if possible matching it with the memory QVL of the board.

If you want to drop in a new processor, you will need to reinstall your OS. On that note, you should keep in mind that the 32bit architecture of Windows' OS environment allows for a maximum usage of 3.5GB while a 64bit architecture will allow for above 4GB usage by the OS.
 
You'd better check out the link in my sig. before you tell someone you can't overclock a locked BIOS MB. Heatsinks aren't a big issue with a 2 core but there are plenty of good ones available.. New CPU soesn't require a new OS. I swap them all the time. BSEL mod is a hardwired O/C. The BIOS doesn't matter. Voltage can be controlled from Windows using Throttlestop software.
If you click the link,and then click the chart at CPUZ you will see how wrong the above info. is.

A 2GB GPU will use 2GB system memory addresses from the top down to store textures. There will only be 2GB left for the OS. This wasn't a problem back when GPUs had 512MB memory. Ideally 5-6GB would be best for a 32 bit OS with 2GB GPU RAM. but with only 2 slots 8GB is the only step forward. Another option would be a 1GB GTX750TI with a loss in resolution support.
 
He would be overclocking a 65W CPU in a 95W MB.
The BSEL mod doesn't run anything on the MB above normal speed for that MB.
Intel sold C2D based Xeons at 3.5GHz speed rated 80W. So it's just top speed for that architecture.

In fact he could just do an LGA771 to 775 conversion and run that CPU. G41 chpset is listed as compatible.
I think you've made my point.
