My current PC: Core 2 Q6600 @ 3.0Ghz, HIS HD4850 512MB fully stock GPU, HP ZR24W monitor + 37" Samsung LCD TV, 450W Thermaltake TR2 QFan PSU with only one 6-pin connector ( http://www.anandtech.com/show/2670
), Gigabyte MB with P41T chipset.
There are some deals for AMD cards at the moment, and I was thinking of getting a HD7850 2GB. The model I would like to get is a Sapphire Radeon HD7850 Dual-X 2GB (11200-07-20G) because it has the output connections I want (DVI-D, DVI-VGA, HDMI, full size Display Port), and it fits inside my case. But after reading user reviews and searching the net for problems I might face, it seems that many people are complaining about some issues, most worrying beeing flicker when running on a DVI-VGA analogue connection (flicker may not be the best way to describe it, but my english is not that good and I can't think of a better word right now...) and black screens / computer freeze after some time running games. I really need the VGA connection to work properly for my Samsung TV (on my TV, VGA simply works better than HDMI - lower input lag, better image quality, better settings available when in VGA/PC mode, and the panel doesn't turn off when showing a full black image like it does when connected through HDMI, which is VERY annoying considering it's a CCFL LCD panel and I can't turn this "feature" off). My current HD4850 doesn't have any issues when I use a DVI to VGA adapter.
Also, from what I was able to find out, the HD7850 needs 2 x 6-pin power connections, my PSU only has one available and I would have to use an extra molex to 6pin adapter.
- Do you guys think my PSU can handle a HD7850 and a Q6600 @ 3.0GHz?
- Is anyone with a HD7850 using a DVI-VGA analogue connection and has no issues with it? Could the problem some users are experiencing be due to poor cables or some misconfiguration?
