My current desktop computer is over 5 years old. It came with Windows 7 Pro 32-bit OS and 2 GB of memory. It has an Intel Dual Core E5300 processor running at 2.6 GHz. I'm not sure how much longer it is going to last and over the years with all of the updates that Microsoft has made to the OS plus having to run anti-virus and anti-malware, the system has slowed down A LOT. A system SHUTDOWN or SWITCH USER used to take seconds, but now it sometimes takes a minute or more. Also, web pages take much longer to load than they used to and some of the pages that have a lot of embedded videos or ads are so slow that you get disgusted waiting for them to become usable, Since I may be forced to buy a new system unit anyway if this one dies, I thought that I'd spare myself the pain of having to recover from a crashed computer and just put together a new one.
I purchased a copy of Windows 7 Pro 64-bit from eBay and now I need a system unit to install it in. There are a number of Intel processors available, and I'm not sure which one to buy. I do not play any games, or do anything that requires high power processing. What I mainly want to do is put together a computer that will continue to provide high performance over the next 5 years that Microsoft will be supporting and patching Windows 7. I'm thinking that a Core i7 would be overkill, but will a Celeron or Core i3 really give me a significant improvement is performance? I was thinking of a new motherboard with 16 GB of memory.
What suggestions can some of you make?
