Redwolf0714 :
I don't know if this helps for the PSU but it is a max power atx12v px480rpf and the Case is a ibuypower i-series 301.
Thank you!
Alright so I'm guessing a 480 Watt PSU, and a Mid-Tower chassis...
The following is what I would upgrade to play DayZ at enjoyable frame rates:
-Motherboard: up to you, it has an AM3 socket not an AM3+ so that limits you quite a bit when it comes to upgradability.
-RAM: Upgrade to at least 8GB. 2GB gets you virtually no where when it comes to running games.
-Hard Drive: because your on a budget, you should be fine, but do a clean whip with the hard drive before using it.
-CPU: The CPU you have is EXTREMELY dated, upgrade to an AMD Phenom II X4 970 and you should be set.
-GPU: You have a five year old...
