I would like to upgrade my current setup which is a Pentium Dual Core E5200 with 4GB of ram and a Radeon 5770 1GB video card and a 1TB Black Western Digital drive. I don't play games very often and I mostly browse the internet but with dual displays and 2 chrome browsers with 10 tabs each open at the same time. I also would like to run virtual machines to try out new operating systems. What cpu/motherboard and ram would you suggest? I would also like to keep it on the cheapest budget possible. I will be running Windows 7 64 bit which I already have.
