I couldn't find any posts about this topic, so sorry if this is redundant.
I am wanting to upgrade my desktop pc. It has gotten a little behind on specs and is a few years old (base specs below). However, I don't know a lot about upgrades with all the new tech available. I know I can upgrade the graphics card, but I don't know how much I can upgrade. For example, would a Nvidia 900 series be to big of an upgrade? Also, can I upgrade the processor? I have listed some of the base specs below if anyone has some ideas. I don't have the funds to buy or build a complete new rig. I also don't have any interest in VR right now. Thanks for the help.
Alienware Alpha X51 (the smaller desktop line)
Intel i3 2120 / 3.3ghz: (socket type listed as LGA1155)
Intel h61 chipset,
8 GB DDR3 SDRAM, can support 16
graphics card is Nvidia GeForce GT 545
