Would go with the Tri-X either way, it comes from the factory with that cooling, with the Arctic Accelero you have to install it which in most cases, voids the warranty. The Arctic Accelero works great dont get me wrong, I put one on my MSI 7970, but I had to send it in for an RMA a few months ago and I was lucky I kept everything cause I had to reinstall it all in order for them to take it back, was a pain in the butt.
