Hi guys, I bought a pair of Galaxy GTX 460s (768mb) for $120 in a deal last year for my first rig. They have been great thus far but I recently bought a 1080P monitor and was considering upgrading to the GTX 570, specifically the ASUS GTX570 DirectCU II, since I'm having trouble getting smooth frame rates playing in said resolution. Considering that my 460s are of the 768mb variety, how much of an improvement should I expect with the 570? I have a GigabyteX-58 mobo and an i7 950 cpu. Also, I was wondering if I should be waiting for a price drop with the release of the new 6**** series on the horizon. Thanks for reading.
