And which specifications should the psu have, if I want an 8800gt 512MB to run at its full potential?

650w but 1000w so you wont have to buy a psu when a better compont comes out. i have a 8800gts + the new intel e8400.

I'm not planning to upgrade any further, so a 650W should be enough? And I read some stuff about 20+A on a 12V-rail or something like that. How many amps should that 12V-rail have for a 8800gt? And does it matter how I connect the components to the psu?

And which specifications should the psu have, if I want an 8800gt 512MB to run at its full potential?

I currently have a Acer Aspire M5500-1E77.
That means: q6600, 8600 gt and as psu: a ATX-250PA (1PF).
I'm planning to replace my 8600gt with a 8800GT 512MB.

I'm just wondering which PSU I should buy. I can't find any specifications on the internet of psu's and I don't really know much about computers. Could somebody help me with this?

Is installing a new PSU difficult? Like knowing which wire you have to connect to which part and configuring your bios correctly, so that nothing says 'BOOM'?

I've read on the internet that you can use two graphics cards together to increase performance.

But can I connect a 8600GT to a 8800GT?

Just to put it simple:
Which one is better at playing games?

A ps3 or a pc with a Q6600, 2GB RAM and a 8800 GT 512 MB

I would only have to buy a 8800GT and a PSU, so the pc would cost as much as the ps3.

It's 250W and 12V1=6.0A and 12V2=10.0 A.

It's an ATX-150PA (1PF).

But I don't really get it. The 8800GT only uses about double the energythan the 8600GT and now I have 250W and I should have 450W?
