I have also not heard of Afox so I'm no help there. And 3gb is only really meaningful if you run multiple monitors so I wouldn't make that the deciding factor if you use one monitor. How much cheaper is the Afox?
I only plan on using one monitor. Umm, I'm probably buying second hand on eBay, and both the afox and evga finish tomorrow. The afox is currently at $230, but looks as though it has no interest from anyone, where as the evga is only currently at $160, but has had 8 bids. I imagine the afox would go for around $300, but I think the evga will go for more
