How would xfire of 2 different 5870's work?

post #1 of 9
Thread Starter 
I allready have the card

GIGABYTE GV-R587D5-1GD-B Radeon HD 5870 (Cypress XT) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card w/ATI Eyefinity

but i see newegg has a hell of a deal right now on

SAPPHIRE 100290SR Radeon HD 5870 (Cypress XT) 2GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Eyefinity 6 Edition Video Card

So i was kind of wondering how these things would xfire.

That will work, but you'll only get 1GB Vram and not 2 or 3.

I figured, basically everything will run at the speed/ram of my old card i would imagine. Wonder if it is worth it.
