I can run the shaders 24/7 and have before but it is extremely difficult to mine or do anything indoors because it makes everything so dark when not exposed to sunlight. Also ran into an issue with it sometimes causing chunks to not load correctly and allowing me to see through hills lol. It really is best just for pictures and videos, or the occasional desire to just bask in awe of beautiful graphics in MC .
custom built it myself, picked out and installed every component. Already been a post about so ill just refer you to that thread. Only thing thats changed since that post is I got a Gaming mouse with 12 programmable buttons on it. http://www.minecraftserver.com/forum/threads/considering-buying-a-new-computer.4830/#post-33731
