I just bought the Venomous X after quite a bit of research. Main reasons: it is pretty much the same as the Megahalems, and I'm not looking to break any records, just get a really solid HSF. The Venomous X is lighter, smaller, and you need to buy fans for both of them. I bought the Scythe S-Flex "G" model ( G designates 1900 rpm). I just bought one for now, but you can do two in a push-pull configuration. I went to Koolertek, and found a promo code "HF5OFF" for 5% off entire purchase and this setup was way cheaper than anywhere else (they were also having a sale on the Scythe fans) if you want to check it out. I also bought the Noctua NH-T1 thermal compound because that was the best stuff they had available, but I'm pretty sure the IC Diamond 7 carat is the best you can get within reason.
