i have ... i3 3120m hd 7670m
The fact is; you won't want to crossfire/SLi two GPUs like that as you are just asking for Microstutter for lower frame rates
I still think that AMD Radeon 7670m is the winner for its fast over-clocking speed while nvidia doesn't Really do that much and can't extend to the fullest.
but I think if you combine, for example, with AMD A8 4500m which have aditional HD 7640 APU in, laptop with 740M don't stand a chance, because Intel will never gave so much aditional performance and quality to 740M when AMD can normaly give to Radeon HD 7670M and I didn't saw any laptop that have Intel and HD7670M, anyone have AMD in it. So if the tests shows diffrences between those two like they are close to each other then HD7670 is totally a winner.
por que amd es mejor que nvidia pelotudo.
We recently pulled in some more benchmarks, the GT 740M is now the winner!
why AMD is the winner over here?
