うわっ？これ、勉強に運動神経、全てのパラメータがMAXじゃないか！おまけにお金もカンストするまで貯まってる・・・すげえ。

？、、！・・・。

Whoa?! This character's studying ability, athletic skills — all stats are maxed out! And on top of that, their money is saved up to the point of capping... amazing.

Literal

Whoa?! This, studying [to-に] athletic-ability, all parameters [subj-が] MAX [copula-じゃないか]! Bonus [to-に] money [also-も] counter-stop-do until accumulated [progressive-てる]... amazing.

パラメータ 'parameter' and カンスト (from 'counter stop') are gaming loanwords. カンストする means 'to hit the maximum value / to cap out' — from arcade games where the score counter stops. おまけに 'on top of that / as a bonus' adds further surprise. すげえ is the rough masculine form of すごい. Gaming jargon mixed with spoken exclamation.
