Maybe with retail but Beta.. you don't have a lot of ram and the cpu is a bit older. The game needs a lot of optimization and lower tier PC's will probably cause very frequent crashes freezes and lag pooped situations.
Your main problem is this: Code: Operating System: Windows 7 Home Premium 32-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.130708-1532) Memory: 4096MB RAM Available OS Memory: 3582MB RAM This game have 32-bit version, but it's won't work good at least for now. I think if you want to play PA you really need to upgrade to 64-bit OS. RAM upgrade also might be helpful, 6-8GB is much better choice for PA.
