I already got a corsair k70 a corsair haarpon and a zowie 144hz monitor so I only need a computer rn I'm playing on a laptop whit 20 fps on lowest quality
well then the build I gave you should do you well.
solid parts. And will perform fantastically on any game at 1440p. You won't necessarily be hitting 100+ fps at 1440p with cranked up graphic settings on the newest AAA titles, but if you're like me and balance the settings to what looks good but isn't overkill you can easily achieve higher fps on average.
The 2070's performance is that of a 1080 more or less and of course you can go ahead and overclock it for more performance as well as overclocking the CPU to get more performance there as well.
You shouldn't need to upgrade anything in this system for quite a while, and even then, when you do go to upgrade something, depending on how long you like to wait, chances are you'll only need to upgrade the GPU.|
Just be sure to buy the parts from the retailers I selected for each one in the build list as this will result in the cheapest overall out of pocket cost after taxes and such. The retailer B&H doesn't collect taxes on the purchase unless you live in either New York or New Jersey.
This is of course all assuming you live in the United States.
I assumed you did since you provided a budget using a $ instead of a different currency sign.
