So I inherited an HP XW8400 workstation from my employer. It currently has 2 Xeon 5140 dual core CPUs installed with 8GB RAM. I plan on upgrading to 32GB and a full kit is around $80 online. The spec sheet shows that the 53XX Xeons will work but was also looking at the 54XX series as well. This chipset is the Intel 5000X chipset. The purpose of this is to have a somewhat decent rig for gaming and whatever else until I have more $ to do a full build again. Should I just stick with the 53XX Xeons or just not bother?
