How simple is it to do this? Is it idiot proof because m quite unlucky with computers, anyone have a step by step guide or a video tutorial?

Voltage tweak asus 5850?

Afterburner will only allow you to up your voltage to the max specified by your GFX card's BIOS so you can't push it over its limit. That doesn't mean you won't lock up/crash your PC (most commonly by overclocking the core clock too high) but you're unlikely to damage anything.

is that the software that comes with the asus card package?

No, it's better.
heat will most likely damage it. upping the voltage will make the VRM's + core a lot hotter...

is it safer to just leave it as it comes
True, but upping the voltage to the BIOS limits is covered under the warranty (it's sold as a 'Voltage Tweak' card) - Asus expects you to OC these.
Of course, but then again it's fun to see what you can get 'for free' out of your hardware.
If you wanna try it out, run a gaming benchmark (like Crysis, Resident Evil 5, Batman or whatever) then up your voltage to its limit in Afterburner and add 50Mhz to your Core Clock and Memory Clock and run the benchmark again - you'll see a few fps improvement.
After that you can raise just the Core Clock maybe 10-20Mhz at a time until the benchmark goes wonky or your PC crashes - that means you've hit the limit of your core clock. Then you can do the same for your Memory Clock (this won't likely clock much higher) until you get a crash or your FPS start decreasing.
Once you've found the magic combination that gets you higher FPS and doesn't crash then you're done

where can i obtain these benchmarks to run while im fiddling? can i just run 3d mark vantage?
Yeah, you can run Vantage - I've been testing my Asus 5870 with Batman: Arkham Asylum 'cause it seems particularly sensitive to overclocking. To give you an example of what I've gotten out of mine - here's some benches:
5870 default:
Core Voltage - 1162
Core Clock - 850
Memory Clock - 1200
Batman: Arkham Asylum
min FPS = 60
max FPS = 124
avg FPS = 94
5870 OC:
Core voltage - 1350
Core Clock - 990
Memory Clock - 1250
Batman: Arkham Asylum
min FPS = 66
max FPS = 135
avg FPS = 101
I'm still tinkering to see if I can get more out of it
One last thing - DO NOT enable 'Apply overclocking at system startup' until you've found an overclock that works reliably for you - that way when (note: when not if) your system locks up whilst testing, you can just hit your reset button, reboot and you'll be back to your factory settings.

flash bios? i thought that msi afterburner software did all that for me
I'm not sure if yuzi87 realises that the Asus cards already come with a higher voltage threshold than the other 5xxx reference boards - either way, you don't need to flash your card scorchisio - it'll work fine with Afterburner.
BTW, final tweaks get me this on my Asus 5870
Core Voltage - 1350
Core Clock - 990
Memory Clock - 1260
Batman: Arkham Asylum
min FPS = 67
max FPS = 136
avg FPS = 102
All 58x0 series card are the same, so you can increase voltage on ALL of them via MSI Afterburner. The Asus cards (and MSI) have higher overdrive limits which means you can clock higher.
Aegis, 1.35v is WAY TOO HIGH for only 990Mhz core. I can do 1GHz at 1.237v.

They do? Are you sure about? My Sapphires went to 1.35v without any issue. And Scorchisio can only overclock as far as his cards overdrive limits, its only the Asus cards that have the higher clock limits. There is an unlocked MSI bios, but its not on the stock cards.
BTW, Smartdoctor has a little bit higher voltage range than Afterburner. ONLY works on Asus (flashed) cards.

At those settings (990/1260) it runs stable at 1.350 (and that's as far as the core clock will go without crashing) - if I drop it back to 1.300 it's crash central - no way in heck I can run those clocks at 1.237 - all cards aren't made equal I guess.
That's as far as the memory clocks will go too - at 1270+ I start losing FPS as the memory errors out.

I'm not too worried
The memory is only rated up to 5000MHz anyway and I'm getting 5080 out of it as opposed to the stock 4800 and a 140Mhz OC on the core ain't bad either - mostly I run it at the stock speeds to keep the temps (and noise) under control - as long as I'm getting a consistent 60fps in my games I'm happy

I can't get Smartdoctor to give me any voltage higher than 1.162v as thats the max the slider will go! Oh I have a Asus 5870 lol
