According to your thread, you question is related to profitable mining with GPU so there is no chanse you'll get any profit with bitcoin mining, that's simply impossible on GPUs, there are asics in game for years. But altcoins are open gates for you, even some altcoins which were thought to be asic resistance, failed and GPU mineable coins turn into asic minables where asics had high hashrates and left GPUs in shadow. Personally I wouldn't mine with GPU as for now.
For check of profitability, there were some websites suggested, also check whattomine.com
