I am considering switching from Software Raid5 to ZFS/RaidZ. Now I wonder whether my hardware would be powerful enough. I am running my NAS4Free on
ASUS M2NPV-VM
AMD Athlon(tm) 64 X2 Dual Core Processor 3800+

In the course of switching I would upgrade my memory to 8GB.

Would this hardware be sufficient to achieve the same level of performance I have today?

I think as long as u don't go for encryption your CPU should be fine, but ZFS is greedy for memory, so give it memory as much as you can afford and is possible on the board....

Maybe... What are you using it for?

You see there are two kinds of speed; Sustained transfer, and IOPS. If you are using it as a file server, or iSCSI device, it will be quite fast. If you are mounting databases, or VM images on NFS shares, you may need to do some work. I did about a week of benchmarking and testing to get VMware performance as good as software raid for a NFS mounted VMware cloud.

I am using it as a file server holding mainly my camera RAW files.

Cheers,

Then ZFS will have similar if not better performance than Raid5. The data integrity and snapshots will really be worth it, however.
