I wanted to try to use an Intel board too.
Sorry for missing that in the first post.
You mean Intel brand mobo? Those listed above use the same Intel Chipset as any other Intel mobo, I have an Asus P5E which uses Intel's X38 Chipset. I don't even know of any Intel branded mobo, no one ever requests one. Crucial's Ballistix is some of the best reliable, stable dimms out there with a lifetime warranty. What will your workstation be doing mostly? If your workstation has a lot of things going on at once then a Q6600 or E8400 will do the trick.
Won't be overclocking...but I can't user quad core yet because some of the programs and machines that will be running on a few of the machines may not work well with that.
They're going to mostly be in a banking environment and we did have issues with one machine when we switched to dual core P dual processors.
Right now we have Intel 965LT boards and Pentium D 930 processors with Kingston 800 ram.
