I have one HIS H577FM1GD Radeon HD 5770 1GB 128-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFireX Support Video Card. I would like to purchase another one to put in my system. My motherboard is an Asus p5n-e SLI, nFORCE 650i SLI. I can't find anything saying if it supports crossfire or not. Any advice would be much appreciated. Also if I am able to do it, does my second card have to be the exact some one or can I use the model from another company?
Nothing's forgotten, nothing is ever forgotten
Yeah, you'd be better off with a newer card than a second one. Crossfire isn't very well supported and doesn't really give enough performance gains to be worth the price of another card.
