Hello.
I want to upgrade my system. Recently I found out a old Core i7 3820 in my backroom.
It seems to be okay...
The question is... I don't know if I should go with it and get a 200$ LGA2011 motherboard for it, or go for a whole new motherboard and CPU. My budget for anything else is 410€.
Any ideas?

The i7 3820 is not THAT old. I would either build with it or sell it. It's a great processor though. I would probably just use it if I were you.

That CPU would be a large upgrade on your current system. For 400 EUR you can get a descent motherboard, new PSU and a good cooler (if you don't already have you). The I7 3820 is still rock solid. Even though the 4820 came out, the difference between them is minimal.

Thank you for your response. So, you think it would be more worth to stick to it than go for the newer i7's?

Thanks, I will buy a motherboard for it and I will see if there is a chance to re-use my CM Seidon 120M because I think I lost the screws and stuff for LGA2011 lol...

Hardware store will have what screws you need probably. I have had to go there for coolers in the past.

I have taken in consideration this:

PCPartPicker part list / Price breakdown by merchant / Benchmarks

CPU: Intel Core i5-4670 3.4GHz Quad-Core Processor ($219.99 @ Newegg)
Motherboard: Gigabyte GA-H81M-HD3 Micro ATX LGA1150 Motherboard ($69.99 @ Newegg)
Storage: Sandisk Ultra Plus 64GB 2.5" Solid State Disk ($77.98 @ Newegg)
Storage: Western Digital Caviar Black 1TB 3.5" 7200RPM Internal Hard Drive ($89.99 @ Newegg)
Total: $457.95
(Prices include shipping, taxes, and discounts when available.)

Seems that the gain in single core performance would benefit me more than the all-core performance? (2,182 PSM vs 1,943 PSM).

Given that the 3930k still holds its own against a 4770k, I would say that the 3820 will still do very well. Single core would be fairly close as it has a higher clock speed than the 4670. 3.6ghz vs 3.4ghz. I would rather have the multicore support going forward. Games are heading that direction. Some software already has.

If I follow your suggestion I would get the motherboard and a second 7770 to SLI with my current one:

PCPartPicker part list / Price breakdown by merchant / Benchmarks

Motherboard: Gigabyte GA-X79-UD3 ATX LGA2011 Motherboard ($214.99 @ Newegg)
Storage: Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive ($64.99 @ Newegg)
Video Card: Sapphire Radeon HD 7770 1GB Video Card ($110.38 @ Newegg)
Total: $390.36

I have other option: I get the Core i7 4771 and a new motherboard, and I update the GPU later.
Would be worth it? There is not so much difference between 3820 and 4771. All I want is the build able to do gaming, video recording, editing and encoding with a decent speed.

If you already have a 3820, use that. It's a great cpu.
