So i purchased the EVGA 670 and i saw that it has the PCI-e 3.0, my current mobo is the Asus z77 sabertooth and my CPU is the i5 2500k Ivy, question is should i upgrade to Sandy bridge to take advantage of the PCI-e 3.0? is it a major boost? for gaming like hitman, farcry 3,cod, etc etc.
No not worth it, and you mean "upgrading" to ivybridge.
There's no performance loss by using the pcie 2.0 vs pcie 3.0
Yeah sorry i always get both mixed up.
Ok just wondering, i tried running Hitman absolution on Ultra and the FPS was around 25-30, when i turned the SSAO to medium and the reflection to medium its was better, kinda bother me a bit that i cant Max it out
No it isn't worth it to upgrade from an Intel® Core™ i5-2500K to Intel Core i5-3570K for PCI-E 3.0 since nothing out there is using PCI-E 3.0. And yes you should be able to run at ultra wih your system.
