also what du you think of the card and is it good upgrade from 9800gtx|||It could really stress the power supply when at full usage. It will work well with your system, and will be the best component in your computer. It is an excellent video card and a huge upgrade from the 9800gtx.|||Your CPU will be a bottleneck in some of the more demanding newer games. I have a QX6700 running at 3.2 Ghz and I was CPU bottlenecked with SLI'd GTX 470's in Mafia II. But yeah the GTX 570 will be a huge upgrade over the 9800 GTX. Your PSU should be adequate for a single GTX 570.
