Low fps

[Rorschachs]

Hello, i started playing a first person shooter called "PlanetSide 2" and my fps are about 20-35 (frames per second).
I have no idea in the matter of computers hardware and only a little bit about the software side, and I would really like to know why do I have only 20-35 fps, and how much would it affect my gaming (i read online that it's harder to play when the fps are lower then about 60).
These are my specs:

Spoiler

CPU: Core 2 Duo E8400 3.0GHz
GPX: Radeon HD 7750 Sapphire 1GB GDDR5 Edition
RAM: 4GB
Internet connection: 12MB with cable.

I run the game on Low res (although when i tried running it on medium the outcome was THE SAME)
So i thought it might be a graphic problem but i'm not so sure, if it isn't so please help me understand what it is and where should i ask it.
BTW - In other games such as Assassin's creed 3 and FarCry 3 the game shatters some times AND there is a TONE of lag in Guild wars 2 that makes it impossible to play.

Thank you in advance.
Assaf.

problem is your cpu, this is why you are getting the same fps even when you raise graphical settings.

i have a 2500k quadcore clocked at 5ghz and planetside 2 uses about 60 percent of it.

First of all, thank you for the fast replay.
And do i have to change a computer to get better results or is there any other way?

a core2quad upgrade would help a lot. if you could find one for cheap it might be worth picking up. otherwise you will need new mobo/cpu/ram

Ok thank you again
although i have NO IDEA what it means, as i said before im dumb at this subject,
so if you can in any way give me an advice on which one i should get and the price range i would be thankfull

see how you have an e8400, the e means it has 2 cores.

you want something like a q8400 or q9400 or q9550 or something. it is pretty old hardware so buying it new can be quite overpriced. if u can find one used for 100 bucks or less i would say go for it.

Well that's all.
I'm low at money right now so i guess i will have to wait until i can get it..
Thank you for your help!
