I done some research about the i5 and the i7. I want to only run 1 video card ever; I found the i5 would be just as good as the i7 for that. is that correct ? I know the i5 only has 16 channel for one video card and the i7 has 2+ 16 channel. am I right with only getting the i5 for my setup ?
one more question, this is for directx 11. I heard it was going to support use of multi cores in cpu's. that right? if so would the i7 be better than the i5 for that because of hyper threading? or will directx 11 only use the cpu pysical cores
If you are gaming, you will see no difference between an i5, i7, PII 965, or PII 955. The bottleneck of your system will be the graphics card, so buy the cheapest of the 4 and get the best gpu that you can.
If the system is being built for another reason the story may change.
