I have a Windows 7 PC and just got a new video card 2GB ($45) which gives me the WEI of 6.7 for graphics and gaming graphics. Up from 3.5 rating of the old 512MB card.
I don't play games or editing video but use Photoshop extensively. How is 6.7 different from 3.5 when using Photoshop? Or was I just wasting my money? I just couldn't really tell.
