Is this graphics card a good upgrade for my pc?

Currently no GPU cards are fully DX12 compatible. To get DX12 card you need to wait another more year.
"Also is it a huge upgrade from my current GPU and how long will it last?"
* What is your Current GPU?
* GTX 750Ti is great GPU for 720p [1366x768] Gaming.
* This card will serve you more than 2-3 years at 720p gaming of modern games + this GPU [60W] don't need Auxiliary power Supply.
 


I recently got an R7 265. It performs better than the 750 TI and can run most games at 1080p on medium to high on some triple-a games just fine. I get 57 FPS on Shadow of Mordor with everything on High. Got it for 109$ refurbished. Currently it's 114$. If you wanna play it safe get a new one but Im doing just fine with a refurbished one.
 


THIS card is amazing for 130$. It has decent overclock and it runs most games at 1080p. However you need a 430 watt power supply at least and you should probably upgrade to 8 GB of RAM first to eliminate bottlenecks. Are you using a 2x2 4GB kit or a 1x4 4GB kit?
 


HD 6670 to 750Ti is a massive Upgrade with similar power Consumption, means you don't need new PSU.
Grab the one that I linked you already.
 


You can't just add another 4GB stick & Viola!!!
Your new Ram stick must have to be same Frequency Memory Speed,Latency,Voltage Configuruation as your Old one to run your System properly, otherwise your System will frequently face hanging issues.
You can find all the information either in your Ram or Install CPU-Z.

I would say, Just stick to your single 4GB Ram, since you are on Tight Budget. 4GB is the required ram configuration for Current Modern Games.
