Echoing this. Most workloads don't need dual Xeons, or even more than 4GB of RAM, but an SSD and two big monitors can make even a low-end machine feel like an absolute Ferrari when you're not waiting for Outlook to launch or wasting time otherwise. SSDs are the best productivity upgrade you can buy: $100, maybe $200 per developer and suddenly no one's sitting around just waiting for their IDE to launch.
