Another "Should I buy" thread

[Nunya]

Sorry for creating another "should I buy thread", but there are some specific questions I need answered before I commit to buying this game:

1. Here are the basic specs for my system:

iBUYPOWER Gamer Power 927SLC Intel Core i5 650(3.20GHz)
4GB DDR3
500GB NVIDIA GeForce GTS 250
Windows 7 Home Premium 64-bit

I'm sure my system can handle the game, but at what level. Will I expect serious fps problems? Will an increase in RAM help? What graphic level will should i expect?

2. I have Hughes Net satellite internet with a max daily download of 200mb. After I hit 200mb my internet speed really decreases. Does the internet piracy protection system send a lot of data back and forth that will max my limit quickly?

3. I am an experienced SH3 & SH4 player. One thing I like, but wish they would improve on is crew management. Is crew management represented in SH5? Is it improved?

4. In SH3 & 4, I set up my own targeting solutions. I hated just "locking" onto a ship and firing. How is it represented in SH5?

5. And lastly, I can handle "minor" bugs. Is there anything "majorly" wrong with SH5?

Thanks in advance with all of your help.
