Neither is ideal being different sizes but having two sticks generally should be faster I believe.

Not sure how it works these days but it used to be unequal sizes would mean you'd get dual-channel speed for the first 4GB on both sticks (so 8GB), but once that fills up performance would drop to single-channel for that last 4GB.

I'd normally recommend just getting a matched kit, but on a Pentium I'd be surprised if you're doing anything with it where you'd notice the difference.

In terms of how the system feels, you will likely notice the 12GB or RAM more than the faster RAM. 4GB just isn't much memory these days, most web browsers will eat that up quickly.
