I am planning on buying a new computer for next year. It will primarily be used for gaming. I am undecided on what parts are better and to get. Any help will be greatly appreciated! CPU - Athlon X2 4600 or Core 2 DUO E6400! they are both around the same price, and i am pretty sure that the Core 2 DUO E6400 is more powerfill than the X2 4600. GPU - i am thinking a Radion X1900GT 256mb DDR3 from powercolor. RAM - i will most propably be using DDR2 and i hope to get 2gb's of it. i am abit confused with all the numbers tho, higher MHZ is better right? what about the timings and latency tho??? HDD - higher cache is better right? i mean there is like no price difference between 8mb & 16mb chache hard drives. But what is the cache? wat does it do? and finally can all LGA775 socket mobos run a core 2 duo? or does it have to be a new like core 2 duo enabled mobo?
