No idea on exact figures, but I've always gotten really good value for money by buying high-end previous-gen PCs instead of current-gen mid-range ones.
I'm in a similar predicament. I'm using a Radeon 6450 HD card and it's old. Around 2011, I believe. Anyways, I was looking to either get a new PC or build my own. I've researched both CyberPower PC and Dell, and heard mix reviews about CyberPower PC; people keep saying they are having problems and having to send the system back all the time. With Dell, I've had two Dell PCs and they both have been fantastic. Now with NVidia coming out with some new technology, I'm wondering if I should wait till Christmas. And even then, buy a PC or build my own.
I've been laptop master race since about 2005. I've had three Dells, an HP, two Acers and a Toshiba during that time. The Dells are without a doubt the most reliable.
Current model is an Inspiron 7559. The i7, 4K display variant, of course. ---
