I've got a 750T-bird socket 7 variety, I cant even give it away, if you spend $175 on a old cpu youre nuts, I'm afraid with a old pc like that youre stuck with it the way it is, upgrades are just too expensive for what you get out of them. Your pc is just old, for $299 you can get a pc that would blow the friggin doors off of yours, its just a fact, some machines like fine automobiles can be thought of as classics when they age....computers just get old, period, you dont have wine, you got vinegar.swrobbie said:I have a Compaq Presario 5838 desktop (purchased new in 1998). It came with a AMD Athlon K7 500MHz processor. I would like to upgrade the CPU to make it faster. I don't want to buy a new system. I spoke with HP and the mother board will only handle up to 1GHz speed. Would it be best to change the CPU to the AMD 1GHz "Thunderbird" or replace the mother board and faster CPU? I am currently running Win98 but will upgrade to XP in the near future.
