So, I currently have a BFG 9800GT Green Edition and a Gigabyte 5670 1GB at home. I'm wondering which will give better performance (I can/will OC as well). The 5670 seems to be alright, but I'm definitely in need of an upgrade, but I'm just going to hold off a tad longer, and thought, hey, maybe I can get a little better FPS with my 9800GT.
The 5670 is a tad better than a normal 9800gt while it will beat the eco hands down. Keep both cards and if you board has a second pci-e slot you can use both cards with the 5670 as the main card while the 9800gt eco as a dedicated physx card. So to say best of both worlds and all without needing pic-e power cables
