Do i need to overclock?

Last response: in Overclocking

Hey, i currently own 1 Radeon 5850 black edition, and i am thinking about acquirering a second one.

So my question is, do i need to overclock my CPU (i720 2,67 ghz, quad core) or will it be fast enough to get the full usage of 2 radeon 5850's?

Thanks in advance.

Two 5850's will perform like a bitch on your system. You might need to punch up your CPU a bit yes. I cannot find a CPU like you mentioned that fits your description, so I take it you have the i5-720? If that is the case, you need to OC a bit to fully realize the power of the two 5850's. I'd say getting an aftermarket cooler (Cooler Master Hyper 212 +, Thermaltake Frio, etc. etc.) to handle the extra heat is a good idea, then OC to 3.2GHz~3.5GHz. You'll be needing around 4GB of RAM as well to not loose on that area, preferably in the 1600MHz range, but 1333MHz will suffice just fine as well.

You don't need to but you should the I7's are begging for an overclock they easily produce a 1/3 to 1/2 more performance.

I also thought about getting a 2nd 5850 but decided against it after reading about certain probs people have encountered. I rather wait for a drop in a price on a 5970.

Hey sorry i missed a letter. It's a "Core i7-920 8mb"

Okay, to make it alot easier for you, here are alle the specifications:

Intel Core i7 CPU 920 @ 2.67ghz (8 CPU's) ~2.7 ghz
6144MB Ram
ATI Radeon HD 5800 Series (5850 black edition)

I only currently running with a 1440x900 resolution, but might be changing monitor in the near future.

What i can deduce from the test results here, 2x 5850's produce on a very high level, and where i live a 5850 cost around 200$ right now, while a 5970 still costs around 900$

But now you now specifically what CPU i have will it be necessary to OC it (probably yes), how much will it need to be Overclocked, and can it be done without buying a cooling system?
