DDR3 yes.. but none of the LGA775 mobos supports PCIE 3.0 its Only Available from Z68/Z77 chipset onwards and also onlo if you couple it with Ivy Bridge CPUs

also upgrading the mobo will not yield you any performance gains, so if you want USB3.0, you can opt for an extension card off of the existing mobo pci lanes (if any) but other than that... you will need more budget to get a good upgrade
