QX9770 is an Intel's CPU with unlocked multiplier for LGA775 platform. Standard clock is 8x400. CPU is less common than QX9650 but it overclocks very similar. The problem is with Intel's decision to use C0 and C1 die revisions for extreme series cpu's of that era, while E0 is much better suited for overclocking. Unless you are planning to extreme overclock it (with LN2 or dry ice) then there is really no point to buy this model. Locked Q9650 E0 revision will do better clocks under more commonly found cooling solutions and modded Xeon X5460/X5470 will do much better if your motherboard can support it.

Like title says, best processor for the LGA 775 platform. However, if you have a LGA 775 motherboard that doesn't support DDR3 ram(the LGA 775 was split between DDR2 and DDR3), then you might as well get a newer processor like the i5/7's because ur gonna need a new motherboard to support this processor. However, if you have a good motherboard, and a good video card(I paired my QX9770 with a Nvidia GTX970) then you should be able to run any game out there(at the time of this writing) at 50-100+fps @ 1920x1080 with max settings. If you want to run VR, forget it. If you want to do 4k, maybe with a beefier vid card than what I got.

Excellent processor ! until i get this QX9770 ( fsb 1600 ), i was using a QX9650 ( fsb 1333 ) on a stricker 2 extreme motherboard with 8go DDR3 corsair DHX and 9800GX2 ... now the 9770 associated with ocz vertex2 120go give me more pleasure to use my computer, because it's became very too fast !!!! a great buy ! i don't regret !
