Your PSU, Ultra 3X 1000W, was reviewed by several sites, in 2007. 18 years ago. You may consider replacing it. The alleged "lifetime warranty" most likely doesn't cover your components. Also by modern standards it actually a 840W PSU, unless anything inside degraded it further over the years.
 
If I purchase a newer GPU, do I also need to replace the motherboard? Thanks Spec are below
No. Aside from changing/updating your PSU, you'll be fine with any current or about to be released GPU.
