I'm pretty new to performance computing. I just built the following computer.
ASRock Z77 Extreme 4 MOBO
3570K overclocked to 4.2Ghz
4 x 8gb Corsair Vengeance @ 1600
700W OCz Power Supply
XFX HD 6670 Core Edition 2GB
Seagate Constellations 500GB HD w 64mb cache
Windows 7 Home premium 64 bit
Is it possible to crossfire this graphics card? The Mobo came with the cables. Does the card I crossfire need to be the exact same?
No the 6670 is not capable of crossfire. It's not really a performance card either to be honest. It's a low end budget card, it's okay for 720p but in 1080p yuou will find it lacking the performance you need.
That's pretty much the conclusion I'm coming too. I've got two displays hooked up, one HDMI and DVI. The HDMI is 1080p 40 inch LCD and I get noticeable horizontal line separation when movies have an action scene.
I only paid $70 for the card so I don't think ebay will loose me too much money. The card plays Prototype and Counterstrike Global offensive well but I know it will not handle newer games.
