Question I want to upgrade my graphics card in my older computer

[Bullet-Tooth Tony]

I built a computer about 7 years ago, I know its outdated but it still perofrms decent in most games. But .. i am thinking i want to upgrade my graphics card. I just dont want to buy much more that the hardware i have would be able to take advantage of. Any advice would be appreciated.

I am thinking id like to find a card with double the Vram , and/or just overall, the highest specs i could go with on this motherboard and cpu. Thanks all .

If your aim is higher frame rates, the i7-4790K may not provide you with that depending on the game. Also depending on your power supply and its age, you may need to replace that if you go with something that's significantly more power hungry than your current card.

As @hotaru.hino said, PSU is very important when selecting a GPU. Some other things that we need from you is to tell us what resolution you are playing at, what games and what is your target performance.

Well back when I had that CPU in my build I was running a GTX 970 then a GTX 1080. At 1080p the GTX 970 did fine with Witcher 3 & Battlefield 1 getting like 90-100fps (but I capped to 60fps due to the 60hz) but when i jumped to 1440p 144hz with a GTX 1080 I was seeing bottlenecks as the CPU was just 90%ing on me in BF1. Only when I switch to my new current board/socket and CPU (bought back in 2016) i did see major improvements with no bottleneck near enough when overclocked.

Current CPU is i7 6800k and I use to overclock to 4.0GHZ at 1.275 volt. I turned that all off once I stopped playing BF1 as the servers went bad.

You can try RTX 2070.
