Split paths almost never result in better performance.
In this case the VGA block is probably a lot less restrictive that the CPU block, and hence flow through the CPU block is a lot less, which means the coolant moves through it at a lot slower velocity, hence the bubbles collecting there.

Ditch it and go serial.

Also watch out for putting a reservoir between the pump outlet and a restriction (eg: two waterblocks in series). Reservoirs are not as easy to get water tight as blocks, and you may get leaks. Ideally reservoirs go immediately before the pump, with as little restriction (think short, high ID tubing) to the pump inlet as possible.
