I plan on getting 4GB of Corsair Dominator 1066 DDR2 next month. On New Egg they have two different sets of 4GB 1066 DDR2 memory. What's the difference in these two types of memory? I don't see any difference other than the price: CORSAIR DOMINATOR 4GB(2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory - Retail $179 or CORSAIR Dominator 4GB(4 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Quad Kit Desktop Memory - Retail $337 Now other than the fact the first one has two sticks, which I thought was supposed to be better, and the other one has four sticks, they both look the same. I plan on overclocking which is why I am getting the 1066 and not the 800. So why is the price difference so drastic?
