Installed the new GPU- absolutely chuffed with the results, a huge improvement over my last one.

Aye, the massive hole in your PC was the GPU. At no point was your original card a "gaming card". The CPU was a high-end one when it was out, an it'll still be absolutely fine.

You have the same GPU give or take as me, and my system flies.


Now that you have a better balance, you could start learning about how to overclock if you fancied it. Its an interesting area tbh.

I'm already dabbling, somewhat cautiously. All of the reviews for this new GPU go on about how far you can overclock it. To be fair it's working great as it is anyway, I'm running older games on it so having no issues with performance. Finally playing Crysis 2 in all of it's DX11 and super high graphics glory!!

Happy for you mate.. now buy Witcher 3 and pre-order Fallout 4 :lol:

Fallout has been pre-ordered since day one.. can't wait!!! When I get through a few of my older games (now in high def!) I'll buy Witcher 3, everyone seems to be raving about it.
 
Did you get the card second hand? If so and your thinking of overclocking id look at putting some new thermal paste on the gpu heatsink. I've just done it with mine using some noctua nt-h1 and its brought load temps down by 6 or 7 degrees.

He should download MSI Afterburner first to get an idea about how it's performing thermally when running benchmarks.

Application of new good thermal paste would improve temps of any card in fairness

That is true, but it might not be needed if it's already working within normal thermal ranges.
I'd not advise a lad who knew very little about graphics cards and PSUs to be dabbling with something like this. Especially when applying thermal paste incorrectly can immediately destroy the GPU if he used the electrically conductive type or more slowly if normal compound is applied too thickly.

As @HebburnMackem pre-empted I ran MSI Afterburner on it. It has yet to go above 69 degrees despite me overclocking it very conservatively on a test run.

I've reverted it to default and it runs in the mid sixties at full pelt. From my limited knowledge that is well within acceptable limits!

70 degrees is nowt.

Is that stress testing it or playing games? Do those cards have a turbo boost feature?
Click to expand...
Stress tested using GPUTool (I think that's what the software is called) - then played a couple of games on ultra settings for an hour or so and checked the temperatures and it hit a maximum of 69c when marginally overclocked.
 
My 7870 had tons of headroom for overclocking, but despite spending hours doing the cpu, I just never bothered.

Maybe cos nothing has ever bothered it so far

I remember getting over 10% on each gpu speed and ram speed stable. But not at the same time. Gave up before finding a stable result.

I done 5% on each and it was perfectly stable so I'm assuming there is scope for more after that. Like you said though, it's coping with anything I throw at it on default at the moment so I'll leave it as is.

On a side note is it simple to overclock the CPU?

It's not necessarily harder but is more involved. It also depends if your board is locked down in the bios. You generally want a better cooler than stock as well as you will have to raise voltages to get the cpu stable at higher speeds which creates more heat. It's generally a case of bump up the multiplier, run prime 95, bump up the voltage till its stable and then repeat until you reach the chips voltage limit/ it won't stabilise/it gets too hot.

Also it's worth saying that the more voltage you put through the chip the faster the chip degrades and will eventually become unstable and you will have to back off the overclock.

I'd also say don't use cpu overclocking software as it normally pumps way too many volts through the chip and better results can be had using the bios.

Sounds like success all around!

I never bothered overclocking my GPU. I've got a GTX 770 so there's not a great deal of headroom to overclock to start with. Had my 2500K running at 4.5GHz for ages now and it's rock solid, amazing CPU for the price I paid.
