You can use ANY HD7950 GPU to Crossfire the 7950 you had!! About the 6GB VRAM, both SLI and Crossfire wont double the memory when you club them. Even though applications may shows 6GB memory its actually 3GB VRAM available to use, the other 3GB stores the exact same contents of the first GPU VRAM
Yeah cheers. I take it I'll need to upgrade my PSU? I have 600w one on the website. Also I'm worried about the cooling of the i5 3570k 4.6ghz oc. Do you think that standard fan will be enough? It will be in a fairly enclosed space as well?
what brand psu?
FSP Premium Grade 80+ Certified 600W PSU so I don't know if that is a good brand or not?
For a system using two Radeon HD 7950 graphics cards in 2-way CrossFireX mode AMD specifies a minimum of an 700 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 46 Amps or greater and have at least four 6-pin PCI Express supplementary power connectors.
Total Power Supply Wattage is NOT a crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important.
Even a Seasonic M12II-650 Bronze (SS-650AM), with its +12 Volt continuous current rating of 53 Amps and with its four (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your intended system configuration. i would get a better PSU
