Opinions - i7 920 @ 4.2 GHz Enough?

Poll Results: Is an i7 920 @ 4.2GHz fast enough?

 
  • 81% (13)
    It's fast enough to keep up with any 2 gfx card setup out there.
  • 18% (3)
    Upgrade to Sandy Bridge and you'll see a noticable difference!

Here's the deal...

I just got an Industrial Design internship that's going to pay me about 8k this summer which is awesome news.

My question is should I upgrade my cpu/chipset and my gfx cards or will a i7 920 @ 4.2 GHz be able to keep up with any 2 gfx card setup out there?

Something to consider I guess, I may want to try a surround 3 monitor setup, ideally at 3x 1920x1200

Sig Rig below is current....

You are at 1920x1200... at that resolution 3.5GHz is gonna be plenty to keep up with 2 GPUs in 90% of games. 4.2GHz is still overkill for gaming at that resolution. There's not going to be a bottleneck or even close.

Will my current CPU and OC bottleneck say two 570 GTX's in SLI at 5760x1200 though?
post #4 of 14
I agree. i7 still does very well with multi-GPU, and at 4.2GHz, it's certainly not a bottleneck.

And my i7 @ 4.2GHz plays GTAIV awesome. thumb.gif Upgrading to a card with >896MB RAM (old SLI GTX260) made a greater difference in GTAIV than Q9550 --> i7 930 for me.

EDIT: At such a high resolution, the CPU becomes even less important than your GPU's. You'll be fine.

Your bottleneck would be less at that resolution... Bottlenecks happen at lower resolutions, and resolve themselves at higher resolutions. If you ran 5760x1200 your bottleneck would be the GPUs because they would struggle to handle that resolution in some games, the CPU would just be sitting there waiting for them to finish rendering that massive resolution.

In short: CPU bottlenecks are pretty much not going to happen at 1920x1200 or higher, unless you are using a 5 year old CPU. The i7 was ahead of it's time, it's going to be fine for years to come if you have it running at 4.2GHz.

Even if you grabbed 2x GTX 580s and ran 1920x1200, you'd be fine. You are far from a bottleneck.

Oops... Didn't see the sig rig until AFTER the vote... >.>

For your current rig, I'd say you're good to go for a while. Heck, I'd still think you'd be good with a pair of 470s. biggrin.gif

It should be okay in all but the most extreme circumstances.

Hopefully your thread doesn't turn into what my did. I asked if 4.4ghz was enough, and I got almost 50 pages of trolling. rolleyes.gif

Only GTX 580 3-way SLI have a chance of being bottlenecked at 4.2 GHz.
