Is my Cpu bottlenecking my Gpu?

[hadi3362]

First my computer specs:
Processor: Intel Xeon W3550 @ 3.07 GHz (4 CPUs) ~3.01 GHz
Graphics Card: Nvidia Quadro FX 3450/4000 SDI
OS: Windows 7 Professional (64-Bit)
DirectX version: DirectX 11
RAM: 8 GB

I can't run Fortnite on it. Is it Bottlenecking or my graphic card is too old? I even get bad fps on Call of Duty MW2 and CS:GO. I want to play Fortnite on it so, should i upgrade my graphic card or cpu or both?

This computer is NOT a gaming machine at all.
The GPU is poor for gaming.
Chance are - I would say not very well at all.
The entire system is quite old, which means you need a big upgrade - sell it is my recommendation.
