Fastest CPU ive ever had

2011-08-03 21:53:52
Posted by: Shotz

Far and away the fastest CPU ive ever had. So many features to make technophiles drool. Too bad it was overshadowed in home use by the sandy bridge-based i7s. Still, loaded up with a dual GTX-460 SLI setup on a good motherboard, there isnt a game in mid 2011 it cant tackle.

Old but good

Ive had mine since release date running at 4GHz on water and it still manages to keep up running with a AMD R9 290 theres nothing it cant run, I also have a 4790K in my other system yeah its faster but this is old and still keeping up :)

Great for VMs

Still using it. The AMD stuff can't beat its virtualization features. I often run a XP or Linux OS in Oracle Virtual Box from Windows 7. I can switch between VMs via the W7 Taskbar, running processes and apps in each OS. I overclocked it and run it on water to max bus rate with 12800 RAM. Never bottlenecks. I'd have to drop $900+ for a 4K CPU + Mobo + DDR4 RAM just to exceed the performance I have here. Great system. Very pleased.
