I don't like the PSU. I would rather go with Thermaltake, OCZ, Antec, PCP&C. PSU's are not something you want to try a different manufacturer.
X800's are not good GPU's as the next gen games will be using PSM3 which the X8 series does not support. You will not be getting your money's worth from it.
But, for your use, it would be alot better getting a Intel. For that price you could get a Intel Pentium 4 820 Dual Core "LGA775 Smithfield" 2.8GHz or a 3.2/3.4ghz prescott. I would go with the Smithfield.
