Ivy Bridge Vs Sandy Bridge - Which to Choose?

post #1 of 35
Thread Starter 
First off I would like to say hello to everyone on the overclock.net forums. You guys really are passionate about computer hardware and I like that!

Anyway, I'm in a bit of a dilemma. I have seen how the Ivy Bridge 3770k CPU's appear to get very hot when overclocking, and it was disappointing for me to see that. Now I'm questioning whether or not I should just upgrade to a 2500k Sandy Bridge. However, the motherboard I bought has the capability to go to PCI-Express 3.0. Now I only play games on a single monitor, at 1920*1080. I don't plan on going crazy and having multiple monitors or anything like that.

So my question is this: Would I lose any substantial performance by sticking with PCI-Express 2.0 over PCI-Express 3.0? I plan to upgrade my video cards (2 GTX 460's SLI) to a GTX 685 (Rumoured to be GK-110) in the future. Would the 685 be bottlenecked by PCI-Express 2.0?

My current build is:
i3-2100 Sandy Bridge
4 Gigs 1600 DDR3 Ram
2 GTX 460 SLI

To answer your question: No, you won't lose any performance, and I think a 2500K would suit your needs just fine. It is the CPU of choice for gamers looking for the best bang for their buck. And it overclocks like a champ.

From what I remember, the performance difference between pcie2 and 3 is minimal, a couple of percentage points at most. Current GPUs are having a hard time filling up PCIE2 lanes. You're not going to lose any real world performance. However if I were you, I'd still wait for detail Ivy bridge benchmarks to come out in bunches. It's only a week away. Although highly unlikely, there may be some secret BIOS tweak that changes everything. Don't count on it tho :>

The performance difference can be quite substantial, but that's when there are multiple cards and usually monitors involved

Right, but the chances of me going multiple monitors is pretty much 0. I may go with 2-way SLI, but I don't think the performance loss will be big enough to really justify PCI-Express 3.0 at this point anyway.

3.0 will probably be more viable in the next year or two

I'd go Ivy, but since you're going to keep your current motherboard it would be more cost effective to pick up a 2500/2600K and clock it hard.

Considering PCI-E 3.0 isn't even supported by any GPUs yet (despite them being labelled as such), no you won't lose any performance. I'd go with a 2500k if you aren't going to use hyperthreading. It overclocks very well and I've heard little to no complaints about its performance.

My current motherboard is compatible with Ivy Bridge though...hence the dilemma.

I would wait for Ivy Bridge, its a week from being launched. Even if it flops ( Which I don't think it will ) you will have seen the newest tech and can make a decision according to facts. I know how it is to wait, its hard but I think you will be happy to know you have a multitude of options not just one you may regret. Just my 2cents.gifsmile.gif
