Hello, this is my first thread in this forum and after searching it for hours, I only got confused. I'm about to buy a new PC but I never tried overclocking anything so I will need some guidance and I hope I can find it here. The system I wanna buy is: Intel Core 2 Duo E6850 Intel DP35DP Motherboard 2x2Gb DDR II 800MHz RAM Radeon HD3870 512Mb Graphics Card I was offered the Sapphire graphics card as well as the Asus equivalent. Also, I was offered the G. Skill 4GB Kit PC6400 4-4-4-12 F2-6400CL4D-4GBPK and the OCZ 4Gb Kit PC2-6400 Titanium 4-4-4-15 OCZ2T800C44GK (which is more expensive but basically the same as the G. Skill kit according to the salesman). Which graphic card and RAM should I take to have a better result with overclocking? Also, is the Intel motherboard good enough or should I take a different one?
