Hi, I've got a question about my overall desktop build and the graphics card upgrade I should get. I've been searching google and several different website including this one and I'm having a hard time choosing between graphics cards and knowing whether or not they're able to be used on my current power supply unit or be bottlenecked by my CPU.
Current build is :
AMD Phenom ii x4 975 3.6 GHz
8 GB Ram
AMD Radeon HD 6700 series graphics card
Gigabyte 990FXA-UD3 motherboard
Core Stream 500Watt power supply
Current graphics card surprisingly runs most games fine, but it's when I want to play my two favourite ones Arma 2 / 3 it begins to start running them really slowly. I understand they're both very CPU intensive but I feel as if it's my CPU causing the majority of the low fps, if someone could correct me. I've been looking at gtx 760's and gtx 660 ti's and I've read that the 760's are better although my current CPU may bottle neck it a little bit. I also read that it requires a 500 Watt power supply, which mine is but with all other components running would it still work?
On my other thread, I was suggested to buy a GTX 750 Ti as it can run on a 300 Watt power supply but I've read that it's slower than a GTX 660? All I'm wanting is a card that can run Arma 2 / 3 on High settings on multiplayer ( A lot to ask, I understand.) Price range would be around £130, hoping I can get a second hand card somewhere as I don't have too much and I don't think I can afford a PSU upgrade.
Any help will really help me on choosing the card I will buy, thank you so much for reading.
