Which HD5770?

I've just built a new rig in a SG03, and my HD4870 512Mb card is causing a bit of a problem with heat; and the fact that I changed the heatsink to an Accelero, which means it's no longer exhausting the heat out the back, is making a bad problem worse. So I've decided to look at the HD5770. It's about the same performance, but lower heat and I've heard the fan on it isn't bad either.

Looking at Scan, there's currently 5 on offer. I was just wondering if there's a massive difference in any of them for the price?

All the same really, just pick the company you are happiest with, Sapphire in my case but it's down to you. Not aware of a particularly good bundle with any of them.

Thought so. Was just wondering if there was a reason for the £20 premium on the Sapphire over the others.

I would say that they are all the same, however the Asus card gives you the option to tweak the voltage (if you want).

If you will be leaving it at stock then go with the cheapest :P
