For Advanced Gaming and Multitasking use the 920 (i7) Processor
29 June 2013
Summary: We have 2 (i7) 920 computers in the house, both are gaming machines and have about 16 gigs of ram in each box, both have dual crossfire video cards and running 64 bit os systems. The Processor is pretty hard to find actually unless you want to pay a good $300 to $400 dollars so when i seen it for sale on eBay for $170 i had to jump on that fast since the other machine we have the processor died. (Mostly it was due to a fan error) not a Processor error.
1st generation i7's rock. If you got the PS these things are great !!!

Summary: This is one of the first generation i7's that started it all. It is quite reliable and overclocks extremely well. It was as advertised. First generation i7's work well but consume more power that the 3rd generation addressed.
Summary: I bought i7 920 processor for my other workstation, I use i7 960 in my main computer. All i7 9xx (except 980X) processors are basically the same processors with higher numbers having greater possible multiplier factor unlocked. i7 920 processor however can be overclocked to reliable 3.6 ~ 4.0 Ghz (overclockability varies from chip to chip) with 20x multiplier and is a great altenative to more expensive chips from i7 9xx series.
