My System Specs

Default Should I upgrade from i5-750 to i7-875K?

Hi guys,

I currently have an i5-750 (no HT) OC'd at ~3.2GHz, but my mobo (Asus P7P55D Pro) actually supports the i7 series, as well. I'm thinking about upgrading my CPU to the i7-875K (unlocked) with HT, but I'm not sure how much of a performance boost I'd see in terms of gaming (Battlefield 3, Witcher 2, Crysis 2, Skyrim, etc.) Right now I can play my games basically at max settings, but I can see that my CPU will be the bottleneck ahead of my videocard.

Should I bother going through the hassle of upgrading my CPU? I'll only do it if there's going to be a noticeable performance boost.

Thanks!

i would move more towards a 2500k build vs getting an i7 for your mobo, but that's just me.

if you have no issues whatsoever,though, leave it be.

i5-2500K isn't listed as a supported CPU for the P7P55D Pro mobo, which is 1156 socket vs. the 2500K's 1155 socket?

No point in going for a processor that's virtually identical in performance in terms of gaming. Even if you had a need for 8 threads an X3440 is much cheaper and will overclock just as well. Not to mention it's an older platform.

If you plan on keeping it for a while, then just upgrade to the i7-875K. You should see a difference in performance.
If your want to get a whole new system, then get a 2500K.

IMO you will see little to no difference in gaming between the 750 and 875. The only way that upgrade would be required is if you are doing CPU heavy computing that can take advantage of hyperthreading (gaming does not). I would NOT do that upgrade if I was you. If you need an upgrade for gaming you will have to make the shift to sandy bridge (socket 1155 and 2500k/2600k).

You wont notice any diff in gaming. I did the same switch last year when I went from a 750 to an 860 and noticed zero gaming difference. Working on the other hand was like night and day.

Thanks for all the replies. Guess I'll save my money until I build a new rig a few years down the road. Might even put it towards a new video card in the near future...those 4gb ram cards will be awfully tempting once they drop down to $300 or so...
