I'm considering to upgrade my integrated graphics card for my ASUS M2A-VM motherboard in favor of a "dedicated" and "separate" video card. That motherboard (if I recall correctly) has at least one PCI Express x16 port. The computer that I have for some time runs very well for about 6 to 7 years without any problems. It can also run Windows 7 as well! Anyways, back to my story: The reason that I wanted to upgrade to a "dedicated" graphics card is that I recently got a new HDTV and I wanted to hook up that HDTV to my desktop computer because it has HDMI ports. I also have two flat-panel LCD monitors too - one of them is plugged in through DVI while the other is plugged into D-sub (Super VGA). I'm starting to move away from SVGA in favour of DVI/HDMI As for which preferred GPU (Graphics Processing Unit) I really like - I tend to choose ATI (ahem, AMD) because of the "harmonious nature" of my system. I'm also looking for a graphics card that has a few DVI-ports (along with DVI to SVGA connector/converters) and at least 1 to 2 HDMI ports. I'm not a gamer however, but I wanted to extend displays to my TV. Which particular brand of graphics card and/or GPU do you prefer/suggest in this case?
Looking at your board I would suggest going for the lower end graphics card. Summet like a HIS Radeon R7 240 around the £60 mark. Your machine is very old really and slinging in a top end R9 280X would be a complete waste of time. I can imagine your case wont even take a big graphics card, they are about 11" to 12" long. They need their own power and I bet your PSU wont be up to the job either. Plus your CPU, just not up to it. It may be getting to the point where a full system upgrade is needed. But I ain't no expert though.
