The horsepower required to process full 5.1 surround sound is miniscule compared to frame after frame of HD graphics in millions of colors. So much of what a sound card does is just passing the audio through. Graphics processing (which is typically highly compressed too) takes a lot more processor power, and RAM space to work in. So technically, a sound card may help, but I suspect the change will be so small, you may not even notice it in benchmark tests. Do you mean RAMboost? Some with low amounts of system RAM feel it helps. The fact is, the idea did not really pan out or get accepted. That is why not many use it. As far as many layers of security, an overlapping security is certainly better than no security, or gaps in security. But more does not mean better. And most importantly, and sadly, what so many experienced and novices alike seem to think is that W7 and W8 need to be treated just like XP. That is wrong! W7/W8 are NOT XP. XP was designed with security almost as an afterthought. Big corporations were more concerned with legacy hardware and software support than they were with security (this in spite of MS wanting to include AV in XP and lock the user accounts down). Microsoft listened and got (and still gets) blamed for our security woes since. W7 and W8 were designed with security having much more weight than legacy support (for which Microsoft got blasted again, but oh well - security really does trump all). You do not need to drive an Abrams tank, while wearing a bullet proof vest and helmet while strapped in with a 3-point harness to be safe while driving. You DO need to drive a fairly new, properly maintained car, and MOST IMPORTANT, you need to drive defensively. That seems like way overkill to me. All you need to do is confirm your primary "real-time" solution blocked anything that tried to get by or that you (as the weakest link) tried to let by. And I don't know what you mean by "none have backups!" That is simply wrong. They are good choice. That is not to say others are not better for some, but if what you claim there were true, there would be 100s of millions of Windows users totally infected. And that is just not the case. Plus I note Microsoft does NOT claim MSE and WD are your total solutions, only part of a full solution. So again, fully updated Windows, MSE/WD and MBAM Pro/Pr together with a decent firewall, and Windows Firewall is just fine, form a formidable defense. The rest is up to the user - regardless the anti-malware software being used. Again, you don't need a monster Hummer or Abrams tank to stay safe.
