I am looking fora low power PCI 2.0 x16 graphics card to upgrade my dell with. I was wondering if there are any cards that use low power but can still pack a punch and be good for gaming. I think it only have a 300 watt PSU and I would prefer to get a videocard without having to upgrade the PSU.
5670 is faster than the GT240. And yes- $44 will let you use any of the 5000 series ATI cards, though for $100 or less, the 5670 is still about the best you are gonna do. The next step is the 5750 which is in the $120-130 range, at which point you might as well just to $150 for the 5770.
