My current System is an AMD 64 - 3000+ with 512mb ram (adata pc 3200).
What my question is, would I be able to tell a whole lot of difference in prformance if I upgraded to the AMD 64 - 3500+ processor? or would the advantages be minimal - My next purchase is going to be an upgrade in RAM to at least a Gig's worth just in case any of you tell me I'd get more performance from an increase in RAM.
clock speed is not the issue when it comes to such a small increase. The ram upgrade is the way to go and while you are at it, with the change you could buy a good graphics card (if you are gaming) then you would really notice the difference.
I had the choice of 3000, 3200 and 3400. I chose 3000 because its only like 10% slower but it was 50% cheaper. So i got the 64bit 3000. I gotta wait for the other parts to arrive before i can build the pc and try it out.
As you already have 512MB of ram additional ram would also make little or no noticeable difference to performance in all but particularly memory hungry applications. A faster hard drive would make a noticeable difference to the time taken to open applications. If you have a 5400rpm drive get a 7200rpm for a real boost. If you already have a 7200rpm drive you would need to set up a raid 0 array or buy a 10000rpm drive to see a real improvement though.
jagx400, you would also need a new motherboard and to upgrade to ddr400 ram. With all 3 upgrades at the same time you would certainly see an improvement.
