The 9590 for example, while still slightly over priced can actually hold its own against a 3930k in streaming at 1080p (tech syndicate said they'd show the benches soon). Is there any benchmark that AMD cpus have a chance of keeping up with intel or is it hopeless? Sorry for the questions I'm a noob and I really want to get into benching, albeit not spending a large amount :s.
All the 3dmark benches are out as they use Physics and Combined tests. What some of us do is compare just the Graphics score from these benches as they are closer to real world performance in games than including the Physics and Combined tests.

On the Unigine Valley and Heaven 4 benches it is easier to compete as they are all about the GPUs. All you need from the CPU is high clockspeeds to drive the GPUs.

Oh cool . It explains why my rig can keep up with similar intel equipped rigs (just about!) in heaven. As soon as I get my psu back its OCing time

Here is my latest benching PC

Some of the guys here asked for the link before I started building it

http://forums.overclockers.co.uk/sho...php?t=18566653

It is up and running now but just needs a bit of tidying up to finish.

Welp. That must be some power draw :O. I knew the 290x were greedy but, oh my :s.

I have not measured it but it must be getting close to 1800 watts when flat out. I tried running 3 cards in another PC with a single 1200i Corsair PSU and the cards were too much for the poor PSU when overclocked.

bahaha, oh noes . Yeah I've noticed the 290 on air is a bit power hungry so I'd imagine 4 290x OC'd to hell must drain a small powerstation's worth of energy.

Fortunately with the 290s cards not using CF connectors if you don't need them all for games you can very quickly deselect them in CCC and just use 1, 2, 3 or 4 in CF. You can even pick which two or three cards you want to CF.
