Currently have

1. Amd Phenom II 1035t (cpu)
2. Nvidia 460 femi (gpu)
3. 2A92 Foxconn(mobo)

which has been a fantastic setup for gaming for a long while but I'll be looking to upgrade very soon with Arma 3 coming to alpha soon, so any ideas what I can do to get the best bang out of my dollar? (ball park 200-400 dollars)

Thanks guys.

ARMA is a special kind of game. It requires a lot of CPU power and RAM. So anything you can do to up those would probably help. How much memory do you have?

@jams: Yeah I know Arma, Been playing it since OFP, and I tend to take it to the max when I start making missions with hundreds of units, thats a rig killer.

It's currently got 4 slots and I currently got 8 gigs of DDR3(forgot the brand but I believe it's dual channeled 600+mhz) .(Ram has never been an issue anything more than 8 gigs of ram tends to be over kill)
