This has always seemed like a really helpful forum, so I thought I would give it a shot.
A (more knowledgeable) friend who I can’t tap up for advice anymore built a computer for me back in 2008. I’ve upgraded a couple of bits over the years - replacing the graphics card when the old one failed and increasing the RAM recently to 6GB (I was planning on upgrading the OS to Windows 8 shortly).
As far as I understand it, to get a modern processor (i3/i5 etc), I’d need to replace the Motherboard, RAM etc, i.e. pretty much start from scratch. If I’m putting off getting a new system for a year or two, is there anything worthwhile upgrading from a cost/benefit point of view (e.g. a new CPU, albeit one a few years out of date) to give it a bit more oomph or am I better off just saving my money for a new computer. No fixed budget, I suspect I am limited by the existing hardware more than price, but to pick a figure I would be prepared to spend maybe £100-150 or so if that was likely to make a noticeable improvement, potentially a little more if that would increase the computer's useful lifespan. At the moment it's a little more sluggish than I would like, but I can probably live with it if that's the better option.
They system is for general home use, some games etc.
