What kind of hard drive?  NVME?

Re: I would like to upgrade the cpu and graphics card but dont know where to start

for gaming improvement consider upgrade gpu first.  cpu upgrade does not bring that much gaming improvement.  your i5 although not an i7 is considered a sweet spot for gaming.

your current config is good for 1080 1440 gaming.  you can upgrade gpu for better 4k gaming.

compared below same rtx 2060 i5-10400 vs i7-10700k, not change in 4k gaming fps.  i7-11700k does not help 4k either if you do not upgrade gpu.

Thanks Red, 
I do use this PC to game and work from home. So I would like to upgrade cpu and gpu. What gpu would you recommend me step up to? 

also would the gpu be plug in play? I know the cpu is a little more difficult to replace. 
thanks

In all honesty, considering the pricing on graphics cards at the moment, you have to do the math and see what is cheaper: a complete new system, or an upgrade.

You will also be restricted on video card options due to the length of the cards that fit in that case.

There's also PSU requirements for video cards, moving the OS over to an SSD or Nvme drive, liquid or air cooling, etc...

These are not really made to replace, especially if you have 0% knowledge of upgrading computers.

In such a case I would recommend purchasing a complete new and upgraded system, especially with the Black Friday sales gong up each day.

You can often get them with a large discount.

Awesome thanks! 
Any idea on what mine is worth?

Uggh VAN. I don’t want a new system lol. I feel like I just got this one. So I’m like 0% knowledgeable on these things? Should I try to replace or just buy new computer? 
I need someone just to tell me what to do lol

some users do buy new Dell pc then take out the Dell oem gpu then resell the rest system minus gpu.  Dell oem gpu price is better than retail but you cannot buy just the gpu from Dell.

Thank you so much for the help guys!
