Help, I can't decide!

Help, I can't decide between the drives:

higher platter density

vs

more space and longer warranty

will the 320gb platter make much difference in speeds? Higher sequential transfer speeds I'm told, but what does that really do in everyday computing?

I can get both at the same price - 130. I've been going back and forth for hours.

Is this going to be an OS or storage drive? I would probably say the 750, unless it's just for an OS in which case you don't really need the space and the platter size of the 640 might be better. Look at some benchmarks.

i only have 1 other hard drive currently and it's the wd2500ks, I suppose i'll eventually transfer the OS / games onto the newer drive, as well use it for some storage too.
