The launch of Intel's Lynnfield processors is slated for next week, but some processors have already found their way to retail stores. HardOCP bought one at Fry's and is one of the first sites to offer a preview of the Core i5 750 processor. They compared the chip against the Core i7 965, but unfortunately they don't provide the actual benchmark numbers because they don't want to ruin their relationship with Intel. You can check out the preview over here. Additionally, some overclocking of the Core i5 750 can be found over here.
The Intel Core i5-750 in our preview looks to be a tremendously worthy enthusiast part even if Intel is labeling it "mainstream." You guys know as well as I do that the true enthusiast parts always have been the mainstream or low-end dwellers anyway. Some upcoming Core i5 models are said to be featuring HyperThreading, but given the pricing structure and performance shown by the i5-750, I have to think that a lot of my overclocking brothers will be migrating to the i5-750.
