I recommend 32gb ram if doing gto+ work, 16 is good enough for anything except bvb srp an few other wide range srp spots like co/btn vs bb if you sim for 200x+ stacks and let it use multiple sizes on all streets
if you're not in a hurry, I'd wait for black friday / cyber monday and get a better deal
this one looks really sharp to me
https://www.eluktronics.com/THINN-15 but it's on pre-order so you'd have to wait until october
getting a better cpu here, these Ryzen 4th gen H series are close to a desktop cpu in performance and as far as I've heard, Eluktronics makes fantastic machines (never owned one tho)
you can find some in stock too from Asus/MSI, but they're going to be big and heavy and priced around 1.2k as well
