You should consider having a mother board with pci express 3.0
Even if you get a moderate level 2.0 card it will still work and you can later get a 3.0 card. Do not go to crazy with RAM. Asus makes great boards. Also, if you want me to build you a pc I can do it I studied IT and have built multiple computer rigs. I would be happy to build you something which I can do easily on a Saturday and bring it on an agreed upon day.
My name is Mike.
I am at the store every Wednesday for Pathfinder, most Thursdays, every Friday to learn Magic, almost every Saturday - unless I am building someone a computer -, and Sundays.
Let me know and I would be glad to help. Do not worry about giving me store credit or any sort of payment. I would enjoy helping out the community when it is reasonable possible. And in this case it is.
