2 x 6770 better than 2 x 4850? Currently have 2 x 4850 and it struggles in newer games with 1920 resolution. Today's newegg deal for 6770 is tempting, should I buy 2? Will I see some improvement? Initially want to go with 2 x 6850 but the price of 6770 is tempting and it will not put load on my PSU too. Want to reduce peak power consumption as my current system underload full load eats about 460 watts :shadedshu with 2 x 6850 I won't be saving much on the power consumption tho. Thoughts?
