OVERCLOCKING: Yes (I want to see how much power I can get from the 5770) / SLI OR CROSSFIRE: Maybe, unsure now.
MONITOR RESOLUTION: 1920x1200 (though idk if the 5770 can handle it)
ADDITIONAL COMMENTS: I am planning to use the AMD Phenom II X2 555 processor, what are the chances that I can unlock the remaining 2 cores to get a quad core? Also, how much can I overclock a 5770 and how much performance gains will I receive? Any aftermarket cooler that I should get?
