What GPU...if money is no object?

Just remember that these cards require a minimum 750w PSU with 42A on the +12v rail or you will probably face freezes, BSODS and reboots. I know some sites, including Nvidia, claims minimum 600w but i really recommend 750w if you don't want headaches. Second, if you do need a new PSU, DON'T go for a cheap one. Buy a known and good brand. You won't regret it.

Depends which PSU hehe...I have Corsair 550VXEU (550W) which is more than enough for my GTX470 twin frozr 2 OCed to 750mhz on core and for my i7920 OCed to 3.5GHz on default voltage. No probs at all...

3 GB GTX 580 is worse than normal/overclocked GTX 580, as the clock of the graphic/shader processor is lower.

You'll have to chose between them considering other factors, mainly the resolution at which you'll run the games:
- if you plan to use normal resolution (like 1980x1080), and most of/the most important of the game you're playing won't exceed 1.5 GB of VRAM (and I don't know of any atm) -> it's better to go with normal/overclocked 580s. For 1680x and lower ones, even a 560 Ti [super][overclocked] or a 570 would be enough
- if you plan to play on surround resolutions (3x1, etc) then you'll need as much of extra VRAM as you can get -> it's better to go with 3GB 580s

And of course the performance of a videocard is greatly depending on how your system can provide and make use of it:
- processor
- motherboard
- PSU
- drivers
- RAM
- OS

Then just get a factory OC 580 3GB like MSI's N580GTX Lightning Xtreme Edition.

Very true. Without a proper CPU, you won't use your GPU to its fullest.

That really depends. Of course a good branded PSU might work with lower watts but it's not recommended because the PSU will be heavy loaded most of the time. Shortens lifetime on several components and in worst case scenario blow the PSU and start a fire. 750w+, 42A on +12 is recommended and i will stick by that any day.

You might wanna throw in another harddisc or two someday or other components drawing extra power, even USB units. There is really no point running a system on the edge.

Personally i'm using the Corsair HX850 Modular unit.

I am wondering, why this little peace of "reasonably priced" hardware is not on the list...

Price in Europe is around 1.300€

because that card is dual GPU, which is same as a SLI on the same card, and therefore has the same problems as the SLI setup.

well I have the power-meter (wattmeter) for PC....you cant beat that ...surprise surprise...btw even if its true (with PSU streching) by then (when my "components degrade) it will be time for new rig...

GTX580 all day. The only reason I decided to go with my GTX560 Ti 2Gb was because I was on a budget. I've got it OC'd up to 977 core clock, 1954 shader clock, and 2205 memory clock. Runs the game very well, only dipping down to about 27-28 fps minimum over land with around 20-25 planes in the sky. A very good buy considering it's almost half the price of the 580. But never-the-less I would very much like to get my hands on one.

Also, I went with a SilverStone 750w PSU. Extremely good quality, 100% modular, and was only $20 more than the standard Corsair 750w at $130 USD. Highly recommended.

Guys thank you so much for your thoughts, I have now decided and ordered a 580 3gb. It is a Gigabyte card, not the fastest around in the class but better priced at £420...if i do not get any betterment over my 480 it is all your fault...
