Building a budget gaming rig ($650~). Going with a 5770 and was looking at picking up a 19" Samsung since it's local and cheap. Native resolution of 1440x900. My understanding is that at lower resolutions games are more dependent on CPU speed as opposed to the Gfx card. Sooo I was looking at a Athlon II X3 455 and a Phenom II X2 555, later being roughly $15 more. Which would be best for me considering resolution and the 5770? I also thought of maybe keeping the cheaper Athlon II X3 and getting a larger monitor for 1920x1080 resolution to rely more on the 5770 than the CPU, the more expensive option. Which would offer better performance? I want to play all newer games, medium maybe some high graphic details. Or is there a better CPU that I totally overlooked? Want to stick to AMD for price/power reasons. Thanks!
