Technically speaking there would be roughly a 2x performance increase.... but 2 times slow is still slow, and the bottlenecks in most systems reside in the HDD, ram, and/or graphics departments and having a faster CPU is not going to help any of those much.
If the new chip is free, then sure, it will be good experience, and there will be at least SOME performance boost out of it... but if you have to pay for the new chip then you would be much better off setting that money asside to overhaul your system with new equipment.
well i've upgraded the ram to 2.0gb ddr2, the hdd to sata2 1tb 7200 rpm,video to 1gb,GeForce GT220 1GB PCI Express PCIe x16 Video Card 533212-001
i just thought it would be fun to do.and it was now i'm ready to build i think?
All HDDs are slow, and even fast HDDs are typically a major bottleneck of most systems. SSDs are the first time that storage no longer becomes the big bottleneck of the system.
DDR2 itself is a major bottleneck. For example, a Core2Duo processor paired with an older DDR2 platorm will feel sluggish, but that same CPU on a DDR3 system feels fairly modern and snappy. Having 2GB of DDR2 is at least enough so that you are not always dipping into virtural memory (using the HDD as memory), but even browsing the web can take up more than 2GB of ram (especially on XP64 or winVista/7/8), so upgrading to 4GB is a good modern minimum for home systems, while power users and gamers really need 8GB to prevent the use of virtural memory.
The GT220 is slower than some modern onboard video cards now. This is still a bottleneck, though no dobut better than the onboard video that came with your computer.
I am not trying to be harsh, or a downer. This is just old technology, and not even mid-level old technology, and any upgrades that you do are going to have serious limitations by the supporting hardware to the point where changing out the CPU is only going to make marginal improvements even if on paper it is a 2x performance increase.
But again, like I said before: If this is a free upgrade, the go for it. There will be some improvements to be had, and it is always fun to work on one's rig.
But if you are spending ANY money at all in order to aquire this 'new' CPU then it is too much money spent.
As a side note... those old Semprons can OC like a champ, do you have a proper CPU cooler to try your hand at that?
