hi i saw the top leaders on this pool and the number 1 was at anonymous 361,046 kH/s 119.4 ltc/day how dose that work? seems like that would be over 100 gpus
I think they're using about 500 GPUs, or at least that's what it looks like from the logs. Still, it probably isn't the largest GPU farm around.
also 290x or Radeon HD 7990 I was going to buy 3 290x but then i saw the 7990 did more unless i read it wrong
Hash rate is not the only thing you should consider when choosing a GPU. Energy efficiency and cooling are also very important. Miners would still prefer 7950s, despite there being faster GPUs. Alas, 7950s are nowhere to be found at the moment. The R9 280X and R9 290X are acceptable alternatives, as is the older 7970. The 7990 is a dual-GPU card, and tends to produce a lot of heat, so you need to make sure you have an adequate cooling solution if you want to use it for mining.
