I currently have a i5 2500k in my system, along with a gtx 680. I was wondering if it would be worth it to purchase a i5 3750k or an i7 3770k. I mostly use my rig for gaming, so that's what I'm most concerned about. Will this increase in performance be noticeable?
Also how complex is it to upgrade a cpu? I'm not really worried about removing it and putting in the new one, as I custom built my pc. I am more worried about the driver aspect of things. Do I have to do anything with the bios or drivers? Thanks for your answers.
Need to know your mobo. Some of them need a bios update to run Ivy Bridge.
But it's not complex besides that, just drop it in. It'd be a better and more cost-effective idea to just overclock your 2500K. You won't see a huge increase in games by upgrading your processor, and those gains would be mirrored with OCing to 4.0 GHz.
Clock for clock, there is not much of an improvement from Sandy Bridge to Ivy Bridge. On average the increase in performance is about 6%. Therefore, no reason to upgrade unless that 6% is extremely important.
As for the motherboard, you would need to update the BIOS (assuming the manufacturer released an update) so that an Ivy Bridge CPU can be recognized.
