Can i put an ATI Firepro V4800 GPU on a Asus M4A89GTD PRO/USB3 motherboard. I've had a look at the various manufacturer's websites and my initial findings suggest that you can't. However I believe from reading this forum that the Firepro v4800 is very similar to the Radeon 5670 which may be supported. I'm trying to build myself a CAD capable workstation on a student budget and am new to building computers, so any info would be much appreciated. Thanks.
