In your case I'd say:
It's not a big deal to buy out of step. Doubly so if your new PC will be a low end one like the previous one, so the new GPU will fit your current PSU. That said, the BIOS might not be compatible with a newer GPU. That happens.
Also, you can buy a used CPU like this one or this one for around $10 on eBay, and you'll have dual cores and a little faster single threaded speed. You can find even faster ones for not a lot more. Again, good to make sure that the PSU can support it, and make sure the BIOS supports it (which is easier to find out than with GPU's). (Also, the Sempron's fan may not be good enough.)
