Need a bit of assistance regarding the EVGA GeForce 9800 GT and the BFG GeForce 9800GT 1GB

  Well, I have been looking to upgrade my computers graphics card for awhile and I am probably going to purchase a 9800GT. It is compatible with my motherboard etc; however, the only problem with it is that it requires a 500W powersupply which means I will have to spend another 100′ish bucks on that as well…which I would like to avoid. Looking around on futureshop I found a BFG GeForce 9800GT which, apparently, only needs a 300W power supply. (which is what I have at the moment) Basically, I am wondering what the some of the main differences are between these two cards and whether or not the EVGA 9800GT is still worth getting the power supply for. From what I can see, these two cards deliver the same performance, expect one allows me to save 100 bucks as I don’t need a new power supply. Any and all thoughts/advice regarding this BFG 9800GT is really really appreciated. Thanks a lot for all help given.
