Help With Upgrading For ARMA 3

[jimabix]

Hello, I have recently purchased the ARMA 3 alpha, and I was disappointed to see how low my fps was (~10), even on the lowest settings. I would appreciate any help / suggestions on what to upgrade. I have a budget of about £200, but I can upgrade parts over time if this needs to be stretched.

Current build:

Motherboard - Biostar n68s3+
Processor - AMD Phenom ii x4 840 3.20 GHz
Ram - 8.00 GB DDR3
Graphics Card - NVIDIA GeForce GTX 550 ti 1GB
Storage - 1 TB
Power Supply Unit - 320w PowerX Stadard

Overclock your processor, that should definitely grab you some extra frames. You should probably get a 7870 XT with the £200, it's a solid card that should be able to handle Arma 3
