You know, as long as you have enough amps on the 12V rail, have a good efficiency rating, and you aren't doing SLi or Crossfire, 450W is enough to cover the 4850 or 9800GTX+.

As for the brand difference, scrutinize the specifications closely. There are often small clock alterations, etc., though the biggest differences are what comes in the box along with the card, i.e. PCIe 6-pin power adapters, drivers, screwdrivers, etc. For ATi, I recommend Sapphire or XFX. For nVidia, I recommend eVGA or XFX. XFX is good because, even though prices are usually higher than the others, they give you a lifetime warranty.

35 amps is enough? The 4850/70 don't seem to tell me what amperage it needs, only the wattage.....What if I try to OC it?
