For both CryptoNight (XMR) and DaggerHashimoto (ETH) you don't need that much computing power but fast RAM. CryptoNight needs relatively small amount of insanely fast memory (eg. CPU L2/L3 cache), while DaggerHashimoto requires large precomputed dataset for mining (stored in GPU's RAM) which is designed such that it is not necessary to verify single hash. The overreaching idea is that the price of hypothetical ASIC miner is more dependent on RAM prices than on random-logic prices.
