Now is a really good time to buy as almost everything has had a 5 to 20% drop in price, due in part to less bit coin mining on certain pieces of hardware. I think you’ll get the most bag for your buck around $1,100.
-1080 video card
(Those 2 will be half the price)
-1 terabyte of ssd (this will feel amazing if you haven’t been using it, and it’s cheap as hell right now)
-2 terabyte hard drive
-16 gigs of memory (this is cheap too right now, don’t buy less)
-motherboard that everything fits on, you probably don’t need to pay attention to this if just buying a computer
I wouldn’t spend less than that, as any lower and your missing out on the i7 and powerful video card/ssd, which is a damn shame! You will notice how amazing it feels to use them. Anymore money and you are paying a ton more for very minor gains.
Get a good keyboard / mouse / monitor, you owe it to yourself to have some good technology. Stick with 1080p or at max 1440p for one more cycle, don’t go 4K yet. The minor improvement in visuals is at a serious hit in performance.
