So I'm getting new parts to build a desktop comp. I was going for an E7400 processor, but the store I went to don't sell those anymore and they recommend I grab the E7500 instead. However, my bro said that E7500 runs a tad slower than E7400 due to something about uneven workload sharing between the two cores.

Can anyone confirm this? Is the diff in processing speed noticeable if I run things like AutoCAD, Pro/Engineering and Photoshop? Any other info regarding the matter is also appreciated.
