I got my new power supply today, after selling my old one. It looks very similar but obviously superior so I should be able to get my computer going at least with low graphics for now and maybe i'll use the 7900GT to at least play some decent games. i'm still wondering if it is worth buying a new graphics card now or wait for the AMD 7000 series to come out next year or maybe even before the end of this year because they will be so much better with the 28nm process. I think i'll probably get a cheap second hand gtx 260 or 275 if I get any money and can't wait any more.
