How as a gamer can you pick the 4770k over the 3930k? Unless you are a complete casual gamer, it makes no sense whatsoever. The 3930k has 40 pcie lanes to the 4770K's 16 meaning at best you are limited to x8 when using two cards in SLI and even worse when you add a third card. The difference is in the 10-15% range when comparing both cpu's with as identical as possible GPU's. Not a huge difference I will grant you, however to any enthusiast gamer, it's a MONSTER difference. The real setback for the 3930vs4770 is price to performance since motherboards, 4 channel memory, the chip itself etc are all going to be more expensive in most cases. Still, a wide availability on sites like ebay or craigslist can fetch you good deals of less that 3 bills for a 3930k which to any gamer, makes it a CLEAR winner over the lackluster average Joe 4770k.
I still use Core2Duo
They just comes out later than the first release of their new cpus :p
Intel does not produce 6 cores processors for desktop anymore?
A fantastic review. I was wondering witch cpu to get and this has now given me the answer. Short fall of it is the i7 4770K Haswell. Reason why? Well its all down to the memory. I want to use a Gigabyte Z87X-UD5H motherboard and this board only supports up to 32GB. The i7 3930K Sandybridge-E supports up to 64GB and that would be wasted. It is also £200 more and looking at these results there is not a massive amount of difference. With trying to keep costs down the Haswell fits in nicely with my budget
