Hi, I was looking into purchasing a new AMD Radeon HD7870 and was wondering if my CPU could cause some bottle necking? I have yet to buy the new graphics card and want to make sure i don't have to completely change my CPU and GPU.

Any suggestions for a aftermarket cooler and some tips on overclocking?
 


What is your budget for an aftermarket cooler?

I don't really have a range for a aftermarket cooler. I never really thought about it. Just give me some suggestions and i'll do whats best.

 


Ok. what motherboard do you have? Because if the motherboard will not support much overclocking, there is no reason to get a beefy heatsink. Also, what is your case?

890GX Extreme 3, and i have no idea what the case is. Is there anyway to find out?
 
No problem :) Also, as for overclocking tips. Overclocking is often specific to the motherboard, but in general, it works by first, raising the multiplier (the multiplier determines the actual clock speed: 41 = 4.1GHz):

The multiplier is highlighted, labeled "Adjust CPU Ratio", and it may be labeled different things on different motherboards, however the function is the same. Next, you need to change the voltage, or VCORE. The CPU voltage determines how much juice the CPU is getting. The higher the multiplier, the more juice the CPU will need. Here is an example of CPU voltage in the UEFI:

I would suggest raising the multiplier one value, and then raising the voltage a little, then rebooting. Once in the OS, test the overclock with Prime95, or a similar program. Errors will often show in Prime 95 within 15 minutes. If the system does not boot at all, then raise the voltage a little more until it does. Rinse and repeat. (Not literally, as liquids do not play nicely with electronics :D) Also, make sure you keep the heat in check. You want to stop raising the voltage if the temperatures get to around 70C. If the overclock is unstable at that temperature, then lower the multiplier and the voltage a little. I like to use HWMonitor to check my temps. Overclocking can often be a lengthy process, so you may just want to dedicate a day to messing around with it.
