Our it dept. is migrating away from Dell and going with HP as our new computer vendor. I've been asked to recommend a system. Our current Dell computers have 2.80GHz Xeon processors. Looking at the offerings from HP, I see Dual Core Xeon 5120, 5110, 5130, 5140.....1.86GHz, 2.0GHz, 2.33GHz available on their xw6400 workstations. I admit that I don't follow the latest processor offerings coming out of Intel and the difference between one or another. I do know that the faster the processor, the faster the computer, but what's up with the 5120, 5110, 5130...numbers?
Any help or advice is much appreciated. I know similar threads come up every couple of months or so, but I'm too lazy to search through the archives for relevant topics.
