A:AnswerUse the NVIDIA GeForce Control panel and set the frame rate limit to 100 fps - Global Settings. Or you can always use a program like Afterburner to try to find a stable undervolt for the card.
A:AnswerNo, this card will not fit in your case. It is nearly 14 inches long (taller then the new Xbox). You'll need a new... much bigger case. Also you wouldn't want to put it in there with that airflow.
A:AnswerDepends on which i7 you have. There are numerous models of i7 cpu's. Saying you have an i7 cpu is like saying I have a 2014 car but not telling you the make and model. Look up system info on your pc and look for what model i7 processor you have and then maybe this question can be answered. Second question....as far as i know there are no 240hz 4k monitors for consumer purchase. Every 4k monitor i see has at most 144hz, and they're a minimum of 800$. They are just now starting to release 1440p 240hz monitors, and i've only seen 2 so far. An HP Omen and a Samsung version. You're going to need at minimum an 8 core/16 thread cpu to keep from bottlenecking this gpu in my opinion. Anything lower isnt worth it for me. For intel that means you need either an i9 9900k, i7 10700k, or i9 10900k. For AMD that means a Ryzen 7 series at least. Idk if this helps you a ton but i answered what i could.
A:AnswerNot unless you overclock them. Checked the evga, asus, and FE and they all have a boost clock of 1.70GHz. The performance difference will mainly come in the design of the cooler of which card is kept the coolest allowing the turbo to be active the longest and the power limit set. Aftermarket cards might have a higher powerlimit but again that only matters if you plan on overclocking the things.
A:AnswerNeed is a tough way to phrase it.... do we really NEED anything besides food, water, and shelter? That being said... your husband could surely benefit from it. And if you get it for him, I can assure you, your chores around the house will ALSO run faster. So really, think of it as an investment in your future... to which I say treat your man right with this card.
