actually i want to play gta v,assassin creed unity and more games which requires only 64 bit os ..
is it possible to install 64 bit windows 8.1 on 32 bit operating system

As long as your hardware can support the 64-bit OS then you can install it.
Installing a 64-bit OS over your current 32-bit will remove all you current data, however, so make sure you backup before you switch over.

my specs are - core2duo, 4 gb ram(3gb usable), 2.80 ghz ,32 bit os x64 based .. will i face some performance issue or processor issue after installing it ??

All processors and motherboard made within the past 10 years or so are 64-bit capable. You will not experience any performance issues after you install your new OS. However, as glamdringfh states, you will need to do a complete OS installation. There is no upgrade path from 32-bit to 64-bit.

Your hardware meets all the 64-bit operating system requirements. You should be fine to upgrade to 64-bit if you want to.
As a technical point, in C++ the size of a pointer (canonically void*) is the "bit" of the OS. In this case, a 32-bit OS has a 4 byte pointer while a 64-bit OS has an 8-byte pointer. What this practically means is, since so much of application code relies on the pointer concept, 64-bit OSes have the advantage that they can address much more memory (2^64 bytes instead of 2^32 bytes) but the code consumes more memory.
The trouble I see is that the GPU is not listed and a Core2Duo at 2.8GHz is very outdated. The CPU should bottleneck most things and especially in games that were mentioned. The other issue is why is there 3GB usable? This is sometimes an effect of Windows 32-bit which won't use all 4GB, or it could be some is allocated for integrated graphics, which were uncommon though still existed on the LGA775 platform.
Unless there's a good GPU here, I think it's not possible to play those games except at low settings. And if there's no GPU at all, then I think that 3GB of usable memory will not go as far and a 32-bit OS would actually run faster. Of course if there is a GPU then that 4th GB of memory is suddenly usable so this is also like upgrading from 3GB to 4GB, which more than compensates for the increase in the pointer size and therefore memory usage of programs.
A possible upgrade would be to look at ebay for a Core2Quad as that will double the number of cores available, and you should be able to find this for $30-$40, more for the higher end ones.

This is incorrect. A system running a 32-bit OS only has 4GB of addressable memory. This has nothing to do with the amount of RAM installed. System resources require some of that right off the top; typically leaving 3.75GB of available address space. A 1GB graphics card installed leaves only 2.75GB of available address space. This means that if the graphics card is in full use and a user has 4GB of RAM installed, the most that can be used is 2.75GB.
Typically, a game's system requirements will only state it requires a 64-bit OS if it also has a minimum system requirement of more than 4GB of RAM.
