This is the only Dual-core desktop i5 CPU. Even my i3 is 17% more powerful than this CPU.
8% worse! damn it
my i5 2320 is 42% better than this cpu
I only need a damn AMD Radeon HD 6850 to be able to ultra any game :)
Oh wow, I thought I was posting on the Core i5-3450 Quad 3.1GHz one xD
I have a Radeon HD 6850 with an i5 2300 and 11GB of RAM and i cant play many games on ultra above 15 fps tops, planetside 2 for example gets about 25 fps on all low whilst in a small battle :/
but its GD rating is 6 JUST !?! its not a good i5
i5 661 is 23% lower than my CPU i3 2120
How dare you Sam…. this is a first generation CPU so it was the first of many great CPUs.
Yea its pretty good!
Great CPU, but a radeon 5770 next to it and you will run games maxed out on a good frames per second rate
I used to use this CPU before I upgraded to a i7-4790K and it play almost every game on high with a XFX R9 270x Double D.
