Today's modern games and many productivity applications can consume upwards of 4GB RAM, so there's little argument for not going with 8GB. However, the need for 16GB of memory is a hotly debated subject, so today we are going see if and where this much memory might be useful for desktop users.
Much of the ECC versus Non-ECC argument comes down to speed versus reliability. The reliability argument at least is easy to validate, but to settle the question of whether ECC actually lowers system performance, we ran a series of benchmarks with standard RAM, ECC RAM, and Registered ECC RAM that all run at the exact same frequency, timings, and voltage.
Undiscouraged by plummeting DRAM prices, AMD has begun elbowing its way into the system memory market using the Radeon brand. The prominent chipmaker has announced three new DDR3 RAM series: Entertainment, UltraPro Gaming, and Enterprise.
