Intel has designed a performance platform for power users and workstations and has achieved its goals in style - for those users, we absolutely recommend the move to Intel's latest and greatest CPUs. But, it's not without its drawbacks for enthusiasts on a budget and for gamers looking for a large jump in performance.
If you're a hardcore PC gamer or enthusiast, you're best being a little more cautious. We'd point you towards the Core i7 920 and ask you to think about your application usage, upgrade budget, and to keep an eye on its overclocking potential (which we'll be investigating later this week).
Ultimately, Intel has made some good steps forward in application performance and if you want to future proof yourself, we'd suggest that this is the platform to buy into and the Core i7 920 is the CPU to go for.
