Upgrading q6600 to 2500k

post #1 of 9
Thread Starter 
Hello! Being new here on oc net I figured I'd ask how big performance boost will I get from upgrading my q6600 (running on stock 2.4) to 2500k (will probably oc it)?

Currently my system is the following:

Intel Core 2 Quad q6600 @ stock
MSI G31M
4gb of DDR2 @ 667 (please don't ask for manufacturer)
AMD Radeon HD 6870 (I do believe that my CPU is holding this thing back)

and I will upgrade to the following:

Intel Core i5 2500K 3.3 GHz LGA 1155
Asus P8H67-M PRO Intel H67 LGA1155 microATX (yes mATX, but my current mobo is mATX too and ATX doesn't fit in my rig)
Kingston HyperX blu KHX1333C9D3B1K2/4G 4GB (2x2GB) 1333MHz DDR3 CL9
AMD Radeon HD 6870

EDIT: Oh and yeah, the PSU is Corsair HX650. Shouldn't have any problems with that?

Massive performance boost. Probably at least twice as fast.

I think a lot of Q6600ers are thinking about this upgrade option since the 2500k is about the same price as the Q6600 was when it was new.

You will see a huge performance increase. Sandy Bridge is about 2-4% faster clock for clock then Nehalem.

I'm doing the same. But since ur Q6600 is stock I think the performance is huge.

Good to know that, and my PSU will have no problems handling the new cpu? I think it consumes even less power than q6600?

Your psu should be fine. I'm runing an oc'd q6600 with a 470 and its oc'd as well with a corsair 750. Since this new processor uses less power and same with the 6870 you should be fine.

Alright, thanks! That's all I needed to know

Yes, it will be roughly twice as fast even if you are running the 6600 with a mild OC like 2.8.

My framerates in games that don't fully utilize the gpu doubled. pcsx2 software mode more than doubled!, games run full speed.
However, most games are not bottlenecked by the cpu even with a tri-sli setup.

If you encounter unplayably low framerate single-threaded games (like mmos, icky engines with asian coding) then it'll be worth the upgrade, otherwise the Q6600 even at stock is still alright for the vast majority of games.

Thanks, yeah that's the reason why I'm upgrading.
