so you mean to say stick with the i3 2100 MSI p67A setup? because the budget dual core will still out preform the AMD quad core architecture even with games that enable more cores or hyper threading?
I do agree with Simon12 you still have the unlocked multi that is Phenom II X4 BE that allows you to OC.
Its still up to you.
I like SB better cuz i am sure that i can upgrade later on to a i7 2600k.But with Amd BD you dont get performance numbers so i cant recommend overall if you do buy the Phenom II X4 you would get more performance now but unpredictable performance later on as BD has got benchies yet.
