|If you're unwilling or incapable of building your own, you're stuck with whatever is out there. How much are you willing to spend? And what do you want to use it for?|
As kuwese stated, all major brands have low end, mid range, & high end products. And none of them actually manufacture anything. They don't make motherboards, CPUs, RAM, hard drives, power supplies, DVD drives, etc. They simply order them from the individual hardware manufacturers, assemble them in a case, then add the OS & additional crapware. And all that crapware is what can drag a system down.
Have you ever wiped the hard drive on your HP & reinstalled Windows from scratch? And I don't mean using the HP recovery disc which will just reinstall the crapware again, I mean doing a complete reinstall using a retail WIndows disc? The difference is like night & day.
