Suggests that there is nothing physically wrong with your add on video card.
Yes I'm using the pc for the same stuff before the upgrade
I was comparing is my fps on CS:GO,
You would benefit from having a better video card but comparing fps using an internet facility such as CS:GO is not a good idea as the quality and speed of the internet connection can have an affect on the results, a better test would be to download and run Unigene Valley Benchmark (free) download from here
the PSU is a DELL L300NM-01
The best card that you could use with the present PSU is a GTX 750Ti but only if there is adequate room inside the case, your computer case is the mini tower type and the present video card the GT 730 is available as both low profile and full height versions, we need to know the type that you have so we have an idea of the dimensions of card that will fit inside your case.
We could do with checking out your present hardware and software to see if there is anything that could be affecting the performance, see below;
Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.
