Looking for people to recommend components for a build that costs between $2000 and $2500. I am upgrading from an older PC and am hoping to be able to use some of the original parts such as: the corsair AX860i power supply, 240GB Kingston SSD, and corsair h100i CPU cooler. I am uncertain if these parts are outdated and should be upgraded or they are fine as is. My intentions for the new computer are completely honorable such as gaming, minor video editing/streaming, and messing around in blender. For gaming I would like to be able to maintain 60+ frames on the highest settings for most modern games in 1440 or 4k (I haven't decided if upgrading to 4k is worth it. My current monitor is an ASUS PB278Q that has a resolution of 2560x1440). When it comes to looks over performance, I am more interested in performance. For instance not everything has to have LED's. As far as the case goes, I would prefer something that can house 140mm fans has good airflow and is moderately quiet. To sum it all up and be frank, I do not know if what I ask for is outlandish for this price so treat the price as rather fluid while still trying to keep to the original parameters.
TL:DR
$2000-$2500
Looking to build a new PC already have power supply, cpu cooler, and storage SSD. (*maybe read above)
Want to game at 60+ max settings on most games, with a resolution of 1440 or higher
Performance over looks
Do not include price of peripherals
Thanks for all the help. This will be the third computer I have built and am still very much a noob.
