AMD Athlon II X4 620 vs. Intel E8400 Wolfdale

I am building a machine for work. I won't overclock and am looking for good stable performance. I typically run dual monitors and have many windows up at a time. Productivity apps, multiple browser windows and remote desktop sessions. I would also like to occasionally play some games but that is secondary.

I put together specs for these two systems, the AMD is about $100 cheaper, and I may even be able to skip the video card with the AMD.

Is the Intel system worth the extra money? I know the 775 is kind of dead end and the AMD system gives me more upgrade potential. What about performance? Any components I should reconsider? All the parts are listed from newegg which is where I will buy them.

Thanks
