I recently upgraded my computer a bit, went from a GT 220 to a GTX 560 and upgraded RAM from 2 to 8, but for some reason I can't seem to get much out of it.
In most games, ArmA 2 for example, I can't seem to hit a fps above 25 at most, even when all graphical settings are at lowest. my friends easily hit 50+ fps with, what I assume, is a similar computer as mine.
my computer is originally about 5 years old, and I have only changed the graphics card and RAM.
These are my computer's specs:
NVIDIA GeForce GTX 560 overclocked to 905 MHz Core and 2396 MHz Memory
Operating System: Windows 7 Home Premium 64-bit (6.1, Build 7600) (7600.win7_gdr.130318-1532)
System Manufacturer: HP-Pavilion
System Model: VN307AA-ABH p6230nl
BIOS: BIOS Date: 08/18/09 11:43:06 Ver: 5.06
Processor: AMD Athlon(tm) II X4 620 Processor (4 CPUs), ~2.6GHz
Memory: 8192MB RAM
Available OS Memory: 8192MB RAM
Page File: 4410MB used, 11970MB available
Windows Dir: C:\Windows
DirectX Version: DirectX 11
DX Setup Parameters: Not found
User DPI Setting: Using System DPI
System DPI Setting: 96 DPI (100 percent)
DWM DPI Scaling: Disabled
A part of this is copied from the DxDiag, I'm not sure which parts are even relevant at all.
If you need more info, please tell me.
I have reset my computer to factory state last month, and now I regularly run CCleaner and defrag, as well as update my drivers, so I don't think that's it

ARMA 2 specifically is much more CPU intensive than most games. So, although you need a good GPU, you also need a good CPU. In your case the CPU is fairly old as it was released in 2009. Unfortunately, in order to get your moneys worth in a CPU upgrade you would also need to upgrade the motherboard.

When I surf on a wireless network can my surfing be tracked?

I live in an apartment building with free wifi to residents. Can the owner track my surfing? Is it safe for me to use my credit card or is it possible for the owner or others to view that info? Thanks.
Answer
Several important things need attention, and will depend on what OS you are using.
Using Public 'Hot spots'; general concepts:
These can be trouble if you don't use extra precautions.
Because 'open' networks have no encryption between your unit and the router, everything you send or receive is in plain text.
So a hacker, with a commonly available application, can intercept and log all of your traffic 'packets'; run "brute force" programs to crack passwords and decrypt all of your traffic at their leisure ("off line").
So the best advice is do not visit sites that are private, or require 'log-in', especially credit cards, banks, on so on.
The only secure method to use, over a 'hotspot' is a VPN.
Note a hotspot that uses "gateway" technology can log all traffic, by impersonating a secure connection, and reveal your SSL traffic.
A padlock indicating SSL may in fact be coming from the router (gateway), which records all traffic before re-encrypting it, and sending it out to the Internet.
Always click the browsers "lock", then examine the pedigree of the chain of certificate authority.
Any weird or strange authority could mean some monkey business going on, especially the final chain link.
Also, when you use a "hotspot" you are by definition in that LAN; and some Windows OS settings open certain ports which can be used to access your computer, by the bad guys.
So for laptops, turn off (aka 'unbind') printer & files sharing, via:
Start> Control Panel> Network Connections> right click 'Wireless Network Connections> Properties> General tab: here, uncheck "File & Printer sharing..."> OK out.
Vista & Win7 have greater breakdown of Network security, but in this case, use the 'Public' settings to shield your system from prying eyes.
Always have a stout firewall.
