Been drooling at the N580GTX Lightening, but it's price tag too painful to look at so have to settle for little sis N570GTX Twin Frozr III PE/OC. but then i saw the MSI R6970 Lightning maybe just as fast as the 580 Lightening but only for for $20 more than the 570. I like Nvidia and have never use Ati/AMD since 03, Which is worth getting? Price watts, power draw, etc... Display: U2410 1920x1200 60hz native.

Leaning more towards 570 PE/OC, share your thoughts, thanks.
