Be careful and check the PSU you have, the 480GTX and to a lesser extent the 570GTX will consume a lot of power. Anything less than a 600w brand name PSU will struggle.

I have a similar setup, Q6600 clocked to 3.6ghz, 4gig DDR2 1600 and a GTX570. I run with Effects on high, land shading medium, land detail medium, building detail and amount medium, everything else high, 1900x1200 no AA (since it's not working) and get 30-40fps over land (15-28 over London) and 40-75fps over water depending on amount of planes. This is with No SSAO and current (as of 4/15 in the AM) patch version.

Truth! When I got my 570 (had an 8800GTS 512) I had a 600W Silverstone Strider. Thought I had enough juice but no, turns out the amps were too low as it was an older ATX 2.1 with 4 12V rails at 18a each. Had to get a new Corsair 750W psu (boo-hoo right, lol).

Yep, same here, I had a HD4870 and went to a HD5870 when they were released. My no brand 600W PSU just would not handle it at all, constant BSODs and lockups. I also bought a Corsair 750 modular PSU, it even runs my Crossfire HD6970s without problems.
