Hi, I'm hoping that there's someone that can help me out a bit here. I recently needed to change my video card from my gforce 8600 because the chip overheated and burned out (the fan ceased working). I replaced it with an XFX Force 9800 gt. Now i'm getting utterly terrible frame rates in games (World of Warcraft). Everything i'm reading seems to point to the PSU not supplying enough power to the card. I'm also seeing suggestions to make sure that a 6-pin PCI-e connector is plugged into the card. Unfortunately, there doesn't seem to be a PCI-e plug on this card. The card is a PCI-e x16 card and it is in the proper slot, of course. On my older card i was getting 50-60 fps nearly constant. Now it's down to 12-30 fps. I'm running on a 550w PSU. Would upgrading the PSU help me out? Any help would be brilliant. Thanks.
