Play WoW and getting Diablo III so I want to build my first system for these games and future proof the build. Money isn't a big issue, but don't want to go crazy so would like to keep the rest of the parts around $1000. I do need an OS also.
Would like to order from Amazon if possible but would swap to Newegg if great deal on part was available.
Any reason not to go with the new Intel chip and associated MB?
Only reason not to go IB is if you plan on doing overclocking over 4,6GHz which nobody sane should even attempt at running 24/7 even with SB.
IB reaches thermal limits at 1.3v so if you plan on overclocking you need to settle with I'd say 1.2v which would be enough for 4,3-4,5GHz at under 80°C during Linpack stress testing if you have a proper cooler that is.
No it's not only 100MHz, IB has roughly 5-10% better performance per clock meaning that 4GHz IB is equally fast as 4,2GHz SB, consumes less power, has far superior QuickSync engine (both performance and quality wise), alot better IMC and GPU etc...
