So I can't compare them but I've had other models of similar boards and didn't notice any different save one and even then it could have been a fluke. One unit the fan failed in days. So back it went.
I'm building a new system and planning on using a Radeon HD4870 X2 graphics card. I ordered the XFX one (http://www.scan.co.uk/Products/2GB-XFX-HD-4870-X2-PCI-E-20-3600MHz-GDDR5-GPU-750MHz-1600-Cores-CrossFire-2x-DL-DVI-I-HDTV) but I've been waiting for it to come back into stock for two weeks so I'm thinking of getting the Sapphire card instead (http://www.scan.co.uk/Products/2GB-Sapphire-HD4870X2-PCI-E-20-3600MHz-GDDR5-GPU-750MHz-1600-Cores-CrossFire-2x-DL-DVI-HDTV). Is there much difference between the two or is it simply price/warranty stuff?
