True, especially with 2 GT1850's in push pull but I guess that ramps the price up somewhat

Super Pi is an irrelevant benchmark though,and is only really useful for comparing similar cores.
Also,it is strange that a 980X score has wangled its way into a PD thread?? A £750 CPU is faster than a £160 one. Who would have thought??

hence the obvious, light hearted nature of the post (and smile) highlighting the irrelevance of cores over performance pal 
And its a 990x, not a 980x

Just got one of these, not had a full play yet. It's 100% Prime stable at 4Ghz at stock volts, but 4.1Ghz is a little flakey, 8th core fails after a few mins. I havent messed with volts yet, not sure how much I'll do since I dont exactly have a great cooler.
Whats a good stock volts clock on these? Also what is the actual stock voltage, so I know where to start

Not too sure about stock voltage but setting the Bios to optimal defaults should provide a clue. I jumped into overclocking it starting with a vcore of about 1.375V setting the LLC to high / ultra high and CPU current capability to 120%.
I suspect stock clocks would be about 1.3-1.35V
My current vcore is about 1.4V under load at 4.7GHz. I have taken it up to 1.5V when extreme overclocking at up to 5GHz.

Had a little play and either my cooling isn't upto it or my PSU cant take the strain.
I have a FX8320. Stock voltage under CPUZ was 1.283v, so possibly 1.3v. At stock volts @ 4Ghz during IBT my plug in meter shows 310w at the wall.
So I crank up the voltage to 1.325v, which gave just over 1.3v in CPUZ and ran IBT at 4.2Ghz, it passed but the power at the wall was about 360w. This is fine, as my old crossfire setup could take this. Temps were about 55c core temp but the socket temp went upto about 75c.
I tried 4.3Ghz at 1.325v but it failed after a minute or so. I cranked it upto 1.35v and ran again at 4.3Ghz, this time it was taking 400w at the wall! then boom my machine turned off. I didnt get a chance to see the temps
My PSU is a OCZ 500w and HSF Arctic Cooling Freezer 7 Pro, nice and quiet but not great at cooling. I think I'm passed the days of jet engined fans and running within 10Mhz of stable/crashing. Tempted to leave it at a steady 4Ghz. I was hoping for atleast 4.2Ghz at stock volts, but I dont seem to be having much luck, just got a AMD 7850 that just manages 1050core, when most can get 1200 easy
