Laing D4 (d5 on the way)--->XSPC Edge--->Maze4--->Alphacool 120.3
Really pleased with this alphacool rad as well....it cost me 20quid shipped brand new and is performing far better than my old HE120.2. Really and excellent budget rad.
Anyway, I turned voltage down a tad to 1.45v load, 1.14v idle and now am at these clocks 100% stable
a stock 4870? it beats it. It beats the GTX 280 The 4870 can clock too though and it will benefit from the extra memory bandwidth, how much it will benefit is to be seen though
