It's been a few months since I've posted here so I kinda wanted to update here with my WEI (and previous one from the "Show Us Your WEI " thread.
The rating of 4.0 is from 2010 with integrated graphics (same motherboard and CPU as the 7.2 rating). No I do not know how I have a 7.0 on the hard drive when it wasn't solid state.
Both of the following ratings are rated on an Intel SSD 520 Series 180gb and an Nvidia Geforce GTX 550ti graphics card and 16gb of RAM.
The rating of 7.2 is from January 1 of 2013 with AMD Athlon II X4 (2.8 GHz) and GIGABYTE GA-880GM-UD2H motherboard.
The rating of 7.4 is from January 11 of 2013 (today) with Intel i7-3770k processor and Intel DZ77GAL-70K motherboard.
The most interesting thing I've noticed in comparison, is that the Intel SSD has better performance on the Intel Motherboard and Processor. Who would have guessed that items from the same manufacturer perform better together
Hope people find this interesting and possibly helpful.
I know now that I've upgraded to the near-perfect current Intel setup, I'll be sticking with Intel from now on.
