DRAM juggler Corsair has just released a document in which it detail internal testing regarding the difference in PC performance when 4 or 2GB of RAM is installed. Named "Gaming Performance Analysis – 4GB vs 2GB," the PDF file includes a small description of the differences memory usage with 32 and 64bit operating systems and, most importantly a test that looks into gaming and multi-tasking performance plus load times when 2 and 4GB of RAM is used in a high-end system.

Corsair conducted the test using Windows Vista Home Premium 64bit with a system consisting of an Intel Core 2 Extreme QX9650, an Asus ROG P965 motherboard (an odd/old choice to say the least), a 320MB GeForce 8800 GTS/ 512MB 8800 GT and 2/4GB of Corsair XMS2 memory. In short, the 4GB system came out on top in practically every test with the biggest difference being seen with task switching and game loading times. As for the conclusion, Corsair states that "4GB of memory is now an essential upgrade for gamers." Not limiting this to gamers, 4GB of RAM is certainly a plus which is becoming more and more relevant and, whether you buy Corsair's memory or not, it almost a must these days. All we need is the money for it.
