[Will-my-pc-run-Arma3? What cpu/gpu to get? What settings? What system specifications?]

i5 650 @3.2 Ghz

4GB DDR 3 Ram

ATI HD 6570 2GB

Can run Arma 2 without any problems.....I have heard that Arma 3 runs better than Arma 2, which I find very unlikely.

So can I run Arma 3 at least on medium? And if so, does it look better than Arma 2 on these settings?

Thanks in advance!

[i've searched 'direct hit' already. Felt that this is necessary. pls read on]

I bought Arma today on Steam and I am stuck on that same mission. It is pretty difficult and that early on.

I have read that the documents are in a small building in the second camp, but I just can´t get near it. The machine gunners always get me or the AI spots me from very far away.

It´s really frustrating, but I will try the above mentioned tactic now and see if I can get the job done this way.
