Now, I bought gtx650 Graphics card from net
I order this

Should i need to change my psu?
If i change gtx650 , install 2Gb of DDR3 Ram and 64 Bit Win7 Os?
Because i don't have enough money for buying new psu
Thanks everyone )

A 500 Watt PSU is more than enough for everything you mentioned. A 500W can easily power even more powerful Graphics cards.

If your ONLY updating from 2Gb to 4Gb I see no reason or advantage in upgrading your OS to 64 bit version at this time.... (32 bit version you have supports up to 4Gb....)

NOTE: adding that 2nd stick of RAM will Speed up your system as it can now operate in "dual channel" mode as it was designed to...

That will leave plenty of money for a good solid power supply (But, you don't need right now....)

Or, a CPU ONLY upgrade, but I'd save up till you can get a nice quad core (just update your BIOS first, the drop in one of these supported CPUs

Ideally something like this:

I don't have AC4 yet, here are the settings from NVidia site: (mostly on "high", but, that dual core CPU will slow you down. SO, you should be about "medium"...)
