Motherboard

I am looking to buya new motherboard for my outdated system, I want ot invest in the athlon 64 technology but don’t know what motherboard would perform better, I don’t want to spend a ridiculous amount of money but want a good performer

any ideas

I’d have a look at Asus A8R-MVP, Asus A8S-X, MSI RD480 Neo2 .
Keep in mind that all are PCIe motherboards.
