Various questions about BitCoin & other cryptocurrencies

[RyuBlade94]

Hi everyone I'm new to this forum, so as everything regarding bitcoin and other cryptocurrency.  I have a gaming rig (i didn't buy it to mine coins, i bought as a gaming pc) with a Sapphire 7950 Dual-X Boost ed (with a XFX 750W PSU. I started mining bitcoins, but then i discovered it wasn't worth it to mine bitcoins. So i switched mining litecoins, for now. Anyway i am not mining 24/7, just 1 or 2 hours a day. That being said, i'm curious about how much you spend when you mine bitcoins approximately, in europe.
Another thing, regarding the hash speed of my cgminer config: i'm mining litecoins on give me coins, and with this config

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS=1
cgminer.exe  --scrypt -o http://ltc-eu.give-me-coins.com:3333 -u Workername -p pass -g 1 -I 20 -w 256 --gpu-powertune 20 --shaders 1792 --thread-concurrency 24000 --lookup-gap 2

i reach around 590KH/s, around 600Kh/s overclocking the gpu. Can you help me improving the hash speed, if possibile ofc?
Last question: what cryptocurrency (even new) do you think is best for mining, now? And it is possible to convert other currencies like, for example, GrandCoin (or any other less known than bitcoin and litecoin) to Bitcoin?
Thanks a lot

Hey Ryu, I'm mining with a 7950 Vapor-X and getting a consistent ~635 KH/s from it. You can check this website for different configs and their resulting hashes/sec: https://litecoin.info/Mining_Hardware_Comparison

I'm on an American college campus so electricity is free I try to keep my rig on 24/7! Here's my config, which keeps the card at a very reasonable temperature:

Code:

 setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -I 19 --shaders 1792 -g 1 -w 256 --thread-concurrency 21712 --gpu-engine 1050 --gpu-memclock 1500 --temp-target 78 --auto-fan -o http://site -u worker -p x
