(2) GTX 470s i SLI mode and PSU size

[mjohnson24]

I got a thermaltake TR2 RX 850watt power supply running (2) sata hd's, amd 1090t, 16gb ram, (1) sata bluray player, (1) PNY GTX470. I added another pny gtx 470 last night and after a few minutes my computer just shutdown on its own. Could it be because the powersupply isnt big enough to run all that and if so what size do i need?

Lol based on the review linked to earlier I would not want their exact same PSU although their offer is good.

Yea thats waht i told him. lol.. But i did go to best buy and take the pSU back and plus since my video card was PNY and it had a 1 yr warranty on it they gave me my money back for the PSU card in cash but the video card they gave me back $325 on a gift card. So im pretty happy. They did it with out hassel so i cant really say anything bad about them right now.

So dont need a power supply right now since i still have my previous 850w. So im in the market for a video card now but my limit is $450. May can stratch it to $500 but pushing it. I do have a few links posted but im limited to whats on the best buy website.

You get more performance out of the GTX570.

 

[mjohnson24]

In what ways? What you mean? Sorry for the dumb sounding questions just wanting to make sure i get my moneys worth is all. But can you tell me how you arrived at that i get more performance out of the 570? Just curious is all. Just want to know the difference between the two is all.

Oh and do we know when nvidia is coming out with the 600 series?

oh ok cool. Now i see. I tried looking some up on toms hardware but most of all i found was them trying to SLI them together for performance. Does anyone know of when the 600 series is coming out and if i should wait if its not too long from know for the release date?
