Hello, Here is my current setup : AMD Phenom II X4 965BE @ Stock Sapphire Radeon HD 5830 @ Stock Antec Earthwatts 650W G.SKILL F3-10666CL7D-4GBRH Ripjaws PC3-10666 4GB 2X2GB DDR3-1333 CL7-7-7-21 Gigabyte GA-870A-UD3 AMD870 Playing at 1680x1050 (22" monitor). 1. Will my CPU bottlenecks the GTX 580 that much ? 2. Do I have enough power for this video card ? 3. Is the upgrade from a Radeon HD 5830 to a GTX 580 worth it ? 4. If not, can you suggest a different upgrade ? Thank you.
