I want to buy a ddr3 video card over a ddr2 video card.
Its the only one listed atm on newegg.com so I get the impression that it's rare for this card.

Just wondering if this improved speed performance takes more out of the power supply?

Getting a low-power Radeon HD 4650 for a compaq cq5210f that has 250w power supply. (thanks for answering that other question guys)

I'm probably just being really nit-picky..

I'm still curious though.

DDR3 from DDR2 would utilize more electricity, but not by much. It's usually more dependent on that GPU.

So if a *DDR2* 1GB Radeon HD 4650 is fine with the power supply...

then a *DDR3* of the same... really makes no difference.

Right?

The power consumption between the two is almost nothing. It is not like you are building an ultra efficient industrial pc or thin client. Plus DDR3 is double the performance of that offered by DDR2.
