Guild Wars 2

Hello guys! Can someone help, if there are any pc geeks here, what do I need to upgrade for my pc to play gw2 on best graphics settings with stable fps and maxed char model limit/quality. Now I play about 60fps and 10-20 fps at boss/wvw battles and in Lion Arch (char model limit lowest/quality medium, other settings was on best quality, tried to lower down but fps pretty much stays the same. I heard gw2 have some issues with amd processors. Game uses like 40-50% cpu. But It would be way too expensive for me to change into Intel. Anyways I don’t really know if its only my processor, but other games like cs:go, crysis 3 works just fine with maxed settings.
Here is my pc info:
Windows 8.1 64 bit.
MS-7623 motherboard
AMD Phenom II X6 1045T 6CPUs ~2.8Ghz
Memory 8192MB RAM
Video card Radeon HD 7870 memory size 2048, GDDR5, Core clock 1000Mhz, Memory Clock 1200Mhz, Bandwith 153.6 GByte/s.
Monitor 1080p.
Help me!

Sorry for bad english:)

What settings are you on specifically?

Not all of the settings are GPU bound, some will rely on your CPU (and some may swap to CPU when on Ultra as opposed to Low/Med/High).

If you want to run the game faster, don’t use AMD or ATI.

I don’t have the particulars, but my friend who’s very, very knowledgeable about hardware interaction with software and enjoys playing with the settings has a lot of information about the topic. He always boils it down to: “Get a good CPU, don’t get ATI, and don’t put everything on the max.”

My settings are all maxed now, only char model limit set lowest and quality medium, vsync is off. Have no problems on leveling zones ~50-70 fps, but if I turn my camera fast it dops to ~30 fps. Lion arch, sylvari city ~24 fps. WvW and boss battles with crowded places goes to 10-17 fps. Also tried on lowest settings, pretty much the same, well maybe I get extra + 5 fps.
Tell me if You need more info.

Turn down/off shadows, they require a lot of resources. Shaders can probably be set to medium. LOD Distance should not be set to the highest value unless you’re scouting in WvW.

There are a few more tweaks to improve your performance, but you should play around with it to figure out what works the best/what you’re comfortable looking at/playing with.

That won’t help me much, that’s the problem ;/ I want recommendations for upgrading my pc, what hardware I need to run gw2 at stable fps. How’s my video card, do I need to upgrade it too and which AMD cpu I need to play on highest settings in epic wvw and boss battles!;)
