You didn’t mention what kind of processor your computer has? But I’m guessing it’s something less than an Intel i7? If this computer is doing what you need, perhaps an OS upgrade and a stick of RAM would make it acceptable? Since you aren’t looking to spend a lot, patching this unit up may be the ticket?
If I had a desktop, with a universal sized case, I’d upgrade the entire thing. A new ASUS motherboard with i5, or i7 processor, these motherboards have a fast front end bus, and can accommodate a lot of fast RAM. And SSD, solid state drives are expensive, but are definitely fast! Many opt for both, a smaller SSD with the operating system on it, and a larger HDD, or hard disc drive, for the bulk of data storage. This will give a lot more space for less money. And any standard video card these days is stellar compared to what you’re used to. But, I’m guessing you really don’t want to get your hands that dirty? It can be intimidating. If it’s something you may consider, check out some YouTube videos on the subject, it’s not as bad as all that.
Bargain computers from the department store can seem like great deals! They brag on big numbers, big processors, but they cheat on the small things, the front side bus is slow and they use slow memory, cheap 2nd grade hard drives, etc. I ordered a computer from Dell, and they were fairly decent, they didn’t cut corners on their main line of desktops, of course their budget computers are cheap like everyone else’s. But, by the time you get the memory upgrade, the SSD upgrade, and the extended warranty, the price can go up!
Like most things, you get what you pay for. But from what it sounds like, you’re not asking a lot from your computer. An i5 with 8gigs of RAM, and a TB of HDD, and Windows 10, should do everything you need for a long while.
It’s been a few years, but I worked with computers for 12 years, there have been a few advancements, but surprisingly little has changed.
