OK so earlier in the week you remeber that I asked you guys about processors for a build I was doing for my dad. Well now I have another build for someone else that he does work for. This computer will be for office work. The person said they don't care what it cost just keep it under 1000 dollars. They also said they want the computer to be fast with good reliable parts. So I can't decide what processor to use in this build. I was looking at the I5 or I7 (2500, 2600 as there is no need for overclocking in this computer) paired with a Z68 board or the AMD Phenom II 975 quad core paired with a FX 990. How does the Phenom II 975 compare with I7 and I5 2600/2500 processor
