2 weeks ago I was at a Microcenter store and picked up a Phenom II 830 O.E.M. (quad core @2.8 ghz with 6 mgs L3 cache0 for $49.99 to use in a rig with an AMD 770 chipset. I was running Windows 8 Developer Preview and the price for the chip was great. Well I got the urge to upgrade my 970 chipset mb from a Phenom II 965 to a Thuban 1100 so yesterday I switched out the Phenom II 830 for the 965 BE on the 770 mb. Unfortunatedly when the new Thuban came it had a broken pin so I had to RMA back to Newegg ( they were great BTW). There I sat with a 970 rig with 2 460GTXs in SLI without a CPU---GRRRRR.
I thought no sense putting the 965BE back in because the RMA process should have me a new Thuban 1100 CPU from Newegg in a few weeks and I already had it running well in the 770 mb with Windows 8. I had the Phenom II 830 sitting there "without a home" so I slapped it into my 970 chipset rig, put on a stock cpu fan and fired it up. Was playing COD MW3 multiplayer for 2 hours without a hitch. I hardly noticed a difference from the 965BE.
BTW I also have an Intel 2500k rig @4400 with 2 5850s in Crossfire and yes it's faster, BUT that Phenom II 830 played very well without a hitch.
