Greetings, After Effects community:
I am considering a computer with a Radeon HD 7670M 1GB GDDR5, I believe. Will this be sufficient for previewing HD video without more than, say, 5 seconds of lag? Thank you!
P.S. I think previewing is mainly GPU-based, but if needed, I am running the Intel i5 3570 processor.
The GPU has nothing to do with such matters in After Effects.

RAM previews need to be calculated and while at times this may go quick, another time you may simply use heavy effects or other stuff that requires to be calculated first. There simply is no way to guarantee realtimeness for everything in AE, no matter how much resources you throw at it.
Thanks, guys! What I was trying to say was when I'm scrubbing through footage in After Effects, it lags like crazy on my mid-2010 Macbook Pro (Intel Core 2 Duo [2 cores, 2.4 GHz], Nvidia GeForce 320M 256MB, 4GB RAM). With the new computer (Intel i5 3570 [4 cores, 3.4 GHz], AMD Radeon HD 7670M 1GB GDDR5, 10GB RAM), will there be little to no lag?
Update: I transcoded my footage from my camera's codec (I use a Canon T4i) to Apple Prores 422 and things seem to be going extremely smooth.
