I am waiting on testing it out until i see a definitive how-to for the GeForce FX 5900 Ultra card I have. This cost me $500 bucks, and there is NO WAY in hell I am going to try and experiment with getting the, what looks to me, a solid piece for ram sinks, and gpu cooler set.
I am afraid I might break something, so i will let someone else do some experimenting first. 8)
