let us know how it goes - AMDs CPUs arent as powerful for gaming as Intels CPUs. That's a great processor, but i feel that it's still holding you back.
Get that CPU stable then check your fps. After that, just get another 7970
I believe, if I can remember correctly, 6100, when overclocked to around 4.2 or 4.4 GHz was, then, able to match i3' performance
Do let us know anyway how it goes
I use the BIOS, easiest way is to bump up the Multiplier, it works in simple terms like this
FSB is 200MHz
Multiplier is x17
200x17 = 3.4GHz (That is my CPU config)
Bump the multiplier from x17 to x18 and you get another 200MHz = 3.6GHz or 3600MHz
Same if you up the FSB, 200>210 x 17 = 3570MHz
But increasing the FSB will also OC your RAM so best to stick with the multiplier unless you want to try OCing other things too
If you get a bluescreen or no boot, bump the CPU voltage up a tiny amount
My CPU from 3.4GHz to 4GHz = from 1.35v to 1.49v but always try to stabilize the OC with the least amount of voltage
well im currently at 4.11GHz and appears to be now stable after a couple of minor cranks of the voltage. i had only two freeze ups, mid game. no bsods. didnt take much additional voltage to get her stable either. May push her a little further tomorrow. added 0.4 onto my windows score too! think she will go further. but i'll be honest, cant say im noticing much if any increase in FPS in game!
