Calculate how much it would cost to upgrade your existing computer then head over to Tigerdirect.com and view what they have in refurbished computers. Many have a year warranty. You may find a better deal in buying one then upgrading your system.

I have ordered a number of refurbished computers from them. I only had one bad one but they immediately took it back and replaced it. They are a very reputable company.

When you are at the checkout line and they ask if you found everything say "Why, are you hiding stuff?"

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
