Upgrading power supply and video card

Hey all, I recently purchased an HP computer and I wanted to replace the graphics card, which was integrated, and also a power supply to support it. Here are the main specs: AMD Phenom X4 9750, 8 gigs of RAM, and a Geforce 9100 (which I will replace with a 9800 GTX+). So my main question is, will this work with the computer I bought as long as I get an adequate power supply (500w)? Also, I plan on playing WoW most of the time, so what kind of performance should I expect? Thanks. Here's a link to the computer if your interested: http://www.bestbuy.com/site/olspage.jsp?skuId=9384285%26type=product%26id=1218096181010Upgrading power supply and video card
really any 500 watt + with a good 12v rail will suffice.. its the ball that ties down high end gpus they need good dedicated power..Upgrading power supply and video card

for WoW geforce 9100 is fine me thinks :)
make sure the mother board has a PCI Express 2.0 x16 slot and also switch ur gpu pick to a gts 250, its the same exact card as the gtx 9800+ except it uses less energy and its smaller and newer. also since u have a quad core and that much ram u might wanna switch to a 600w. heres a wattage calculator
