Upgrading Sandy Bridge system and adding new components.

[FinishGamer86]

I was wondering if upgrading (which I am going to do in a few days) my Sandy Bridge main system, will it handle a few modern games at least at 1080p or 900p medium-low settings?  . My motherboard supports up to a i7-2600 non K version CPU, which I obviously intend to buy because why not? It has 4 cores, 8 threads and it's faster 3.40GHz than my 2 core , 4 thread i3-2100 3.10GHz . Now , this is a 8 year old cpu. but since I don't really want to buy another PC which costs even more, I rather save this and upgrade it.

I was thinking about a Zotac GTX 750 ti 2GB (single fan) as a gpu and an additional 4GB DDR3 Memory at 1333MHz , the total RAM will be 7GB total with the additional 4GB (i know , sounds crazy)

The budget I have now is 147.37 euros for the upgrade including the thermal paste.

The budget is the total price what I have to pay when I order all of the components.

What are your thoughts? Will it play a few "modern" games at 1080p or 900p medium-low?
