Tell us your budget? and I’ll have a look but for a reasonable cost 1440p look no further than a Ryzen7 5 series* paired with an rtx3060. All ultra, high LOD, fps in the mid 40’s, or 50’s with DLSS.
*It has to be a Ryzen 5xxx to take advantage of a sizable boost from PBO undervolting, the 5700X and 5800X have eight cores which is a little more future proof than the 5600X’s six … I would only recommend an expensive X3D with at least an rtx3070 or you really won’t see much benefit.
