If you love MH and can pass the benchmark then very much so I would pick it up. If this is your first foray into the series keep reading.
I love this game but given everything around it at this time I cant say I would recommend buying it at this time maybe in a few months, October if I had to guess based on past experience with MH games on PC.
If you have a beefy computer you should be okay but other than that the only place you are going to see over 40fps is in the training area.
Here are some glaring issues that I don't see being fixed ever.
- Character Edit Vouchers are a disgrace
- The Sandtide tanking your fps
- The fact that the water looks better without Ray Trace on
- Certain freezes and crashes when using the sling shot
- The LOD issues, which are funny but seeing Gemma looking like an Age of Empires character gets old quick
- Literally every "DLC" there. $2 USD for some chat stickers... screw off Capcom

most other things have a chance of being fixed in a reasonable time.
