My PC was one of the highest specs at the time, I had the option to overclock it to 4.0GHz but decided it wasn't necessary at the time. If I decide to play games that are demanding then I would do so, as well as get a couple of new graphics cards to SLI but I probably should just get a new motherboard, CPU and RAM.
As for poker, I stopped for around 1.5 years or so, then started again last September for a few months making a small profit of around $1500 but gotten lazy. :/
I started playing since 2006 winning more money year on year. 2009 was my best year winning around $40,000 so I used some of that money to pay for my wedding, honeymoon to the Maldives and the PC project that you see above.
The game has gotten more difficult now and I haven't taken the time to keep up as I have a full time job. I do have friends who consistently win big 6 figures for several years in a row now. Most of them are in their early 20s, pretty sick!
