Now its done me well for the last 3 years but lately ive noticed its starting to slow down a lot, boot in times is a 2 minute wait before I can open anything. Internet browser crashes a lot. Gaming is still okay, play COD 4 and BF2 comfortably on it. My budget is tight however have about £100 (Recession ).
However I have seen I can get a 3Ghz AMD X2 6000 FOR £40 and probably buy a better graphics card for £50, probably means ill have to upgrade me psu to a 500 w + thou. Ill reinstall xp and keep me old monitor.
...... Is it worth it thou, I want to be playing the newer games out now like BF3 and Rage, and I dont want to spend the £100 to find I cant play them. A friend told me to sell the parts and with the £100 buy a barebones bundle from an online retailer !!
My honest opinion would be not to put anything into your system that can not be reused in another new system. I would not invest in a new CPU as it won't buy you much. Maybe if you got it for free or dirt cheap. I'd probably throw in a new video card/power supply and then save for an entirely new system.
