Is my graphics card broken?

[Someone other than you]

I have a gtx 670 and a core2 duo which I know is a bottleneck but I only get ~20fps in most games. My brother also has a core2 duo but he has an old gts 450 and gets 80+fps

Please help me

Does your brother have the same model of core 2 duo / play the exact same games?

Alright. And what are the games you're both running, what is both of your RAMs, and are your operating systems 32 bit or 64 bit?

are you using the right output to the monitor?

are you both running the same game resolution?

We both have 64bit and DVI-D to the monitor. He has 1440x900, I have 1600x900.

Ok so i put his graphics card in my computer and turns out it runs just the same. Think I might need to reset my hard drive or maybe a new one... maybe an ssd
