With 64bit systems and ram cheaper than chips, I just don't understand the term resource hog any more.
That's a term from the low powered, single core cpu days when ram was $200 a gig.
I bought 4gig of ram today for a 3.6gig quad core cpu, it cost $30 !!!!
If you open task manager, look at processes and click on memory to order it descending, you'll find windows is the resource hog, closely followed by your browser.
Who cares if it takes 10 seconds extra to start the PC, get a solid state disk if it's a problem
One things for sure, if you don't run an antivirus and have your identity stolen as a result, you deserve it.
