It's going to be interesting. I've heard so much contrasting information about Intel Vs AMD. I'm curious as heck to see which is better. So... Former Rig Haf 922 Mid Tower AMD 9590 Running at stock- could not overclock this. Probably because my 750 Watt PS couldn't take the voltage. Noctua NH-D15 Gigabyte 999FXA-Ud3 AMD Radeon Gamer Ram 2400mhz Twin Asus Gtx-660 [Not TI] 540 GB Evo My four year old 750 Watt PS just could not take that much voltage so I decided that if I'm going to replace the PS I might as well replace the case. Hey and if I have to do all that work I might as well Sidewise Grade to Intel Mother Board and CPU. I changed my Ram for Two reasons. 1st on a benchmark it came in as very slow. 2nd AS-Rock compatibiliy page had the G.Skill Trident 2400mhz Ram as the only compatible 8gb 2400mhz chip.Sure enough XMP 1.3 Profile 1 recognised it as a 2400mhz chip. No Problem So they say in for a penny in for a pound. Sent the Ram back to Amazon for Refund and my CPU is on Ebay [Auction 161401154001] right now bidding is up to $167.50 hopefully by Sunday it'll be in the low to mid $200.00 range. So I won't' take a really big beating. I chose the 4820 because I hope that my SLI Video Cards running in PCI-3 mode would be better utilized by this CPU. It also has a reputation as a overclocking beast. So far I can get a stable OC to 4600 New Rig AreoCool 540 - Awesome Case, Cubular Intel 4820K Ivy As Rock 79 Extreme 4 G.Skill Trident 2400 mhz ram Twin GTX-660 EVGA Supernova 1000 Watt PS 540Gb Evo So far the Intel seems to run smoother but the verdict is not in yet. Amazingly enough Windows accepted my upgrade and I didn't have to reinstalll. Problem is that I have 4 years of garbage in that system, also stuff left over from the AMD so last night I backed everything up and did a fresh install of Windows. Rock and Roll. Out with the old and in with the new. Anyone have a prediction about which will be the better performer.? I have a few different Benchmarking Utilities including Passmark and Furmark. I'll post the performance as soon as I get done with my testing.
