I don't know how well that tech is.. I like the low cost and performance of the Trinity, but Kaveri is relatively unknown still ... I would love to work with it. The 7990s because I want to see that Sniper mobo handle it, plus I might be doing some 3D work on top of gaming, and I thought the 6GB GDDR5s would be best in that configuration. If they had a GCN video card out that has GDDR 5 and will work great with the Kaveris, then I would have chosen them.
