Hi guys - Building a gaming rig

That's tru Stu

WE like the 670 as it's a cutdown 680 but they cut off very little. A few cuda cores less and a lower clock speed, we can overcome the later with overclocking on the 670.

EVGAs FTW uses the reference design @1000mhz+. They are known to add extra heatsinks to assist cooling on their FTW editions (I've seen this on the 460 GPUs). If you look at the other 1000mhz+ clocked 670s for £300ish, they are sporting the companies improved cooling solutions.

Of course he could overclock on the stock cooler but I thought I'd explain why I called the 670 a £300 GPU

The 7950 once overclocked and on the new drivers is snapping at the heels of the nvidia 670 which is a £300+ GPU.

I've never actually overclocked a gpu strangely - Is it far removed from overclocking a cpu?

I have used EVGA PrecisionX and TGT Bigbang on my GTX670.

I couldn't be simpler.

There are plenty of guides on the net or youtube to show you what to tweak.

TGT BigBang is really simple to use.

Download MSI afterburner.

Nice thing about Afterburner is that it includes an OSD and you can set custom fan speed profiles, there is also Kombustor included to "stress test" the GPUs overclock. The OSD can display temps,FPS, GPU load, VRAM used etc etc. All which can be displayed in game so you can see the improvement your OC has made to the rig

Bit hard on yourself there fella lol

It is. Can be a little time consuming if you are trying to see how far you can take the GPU but you don't have to obsess over it.

I have a 460 in my HTPC. Stock is usually 675, my EVGA came at 763mhz, with AB I pushed it to 900Mhz and improved the VRAM speed considerably as well from 1900 to 2100.

You can also save presets. As the summer months are warmer you might need to step back your overclock. So you can save upto 5 different custom clocks to load at your leisure
