Ok, so as the title says i need a bit of help here. I have a GPU right now in my computer it's a GeForce GT 640. And my processor is an AMD Athlon II X4 2.9 Ghz. Right now running most games i get about 25-40 frames. On high to medium settings. But arma 2 and arma 3 just run terribly slow. Like from 9 to 15 frames. I turn down the settings all the way and i can't seem to squeeze out any extra frames. I don't dare overclock my computer cause i don't know a thing about it and i am not a risk taker when it comes to computers. What i really wanted to know was. What should i upgrade for better performance for all games. A better CPU or GPU because i know that GPU is more important but a CPU also helps a lot. My motherboard is a BQ480AAR-ABA p6527c. If you guys could help me finding a processor (if i need to upgrade) telling me if the slot fits in with my motherboard i'd be grateful. Vice versa with a GPU. I might not be providing enough Info or If i said some things that you had a "WTF is he saying?" moment that's because i only know a bit about these kinds of things. Not a whole lot. Just say what info you need and i'll provide it. As long as it's within non personal info. Here is the CPU i've been kind of eyeing. Tell me what you guys think. Budget is around $0-$250 but if there is good ones that are less than $300 i'll take a look.
-AMD FX 8-Core Black Edition FX-8320 (FD8320FRHKBOX)
-AMD A6-5400K APU 3.6Ghz Processor AD540KOKHJBOX
A new processor would require a new motherboard.
To get the most out of your PC NOW a new gpu, such as the EVGA 660 you listed, would be the best bet.
To get the most out of it in the long run, a new CPU and motherboard now would allow for stronger upgrades later on.
Ok, that GT 640 has GOT TO GO. The Athlon II X4 should be useable but remember that ARMA III is so high-end that [H]ardOCP says that Ultra settings are not useable on any single card today, including the R9-290X and GTX 780 Ti. You CPU is a far better CPU than your GPU is a GPU so that is your biggest problem. Most games are GPU limited so that's another reason to get a new vidcard. Now, you're most likely going to need a new power supply so I took that into consideration and added it into your $250 budget. Video Card - Powercolor HD 7870 2GB - $190 (-$30 mail-in-rebate) Power Supply - Corsair CX-500 500W - $60 (-$20 mail-in-rebate)
Both of those items equal $250 and the difference in your gaming experience will be nothing less than earth-shattering. Enjoy!
As an aside, NEVER buy an APU if you plan to get a video card as well. It completely defeats the purpose of getting the APU in the first place. Always get a CPU with a video card because the CPU will be less expensive and the APU becomes a waste of money as you won't be using its GPU side.
