EDIT: I did find a ULTRA 1600w power supply but i don't know how good of a brand it is.

I am like 99% sure that memeory has no impact on PPD.

I know there is a 1200 psu that was shown to supply like 1600w - let me see which one

So your getting the extenders then? If you are, that should work. If not, then those GPU's won't all fit on that one motherboard.

There's more of a difference between the cards than just the memory. 1GB version also has a larger memory bandwidth, which may have an impact on F@H performance.

As for the PSU, Strider Gold is probably your best bet. There's an FAQ in the Power Supplies section that you should check out, too.

Whatever you do don't buy that Ultra PSU. I would probably get this. With five 160W 460s and a 65W CPU I don't you'll need much more than 1000W but a 1200W will give you the option to expand later.

You can also get EVGA B-stock 460 FPBs for $120 here, though they might not have 5 in stock.

Well its only $40 more for the 1gb so i get teh 1gb. On the PSU the Strider Gold ST1200 should be good enough.

Yessir, I think you're making good choices there.

For what it's worth, those PSU calculators always overstate your needs. That 1200W will be just fine.

There's some good advice above about the EVGA B-stock. If you're not concerned about warranty, you can do that and save a good chunk of change. Did the discount at Fry's thing work out for you?
