I wouldnt bother with the memory option because they charge you too much, and it's easy to replace or add more. The processor and graphics card aren't, so just in case you want it to fly or play games on or whatever, I'd go for the faster options, they can't hurt. 770/780 or whatever is probably bit overkill though, 760 would be fine at 2 Ghz M.

If I were you I would go for 7200rpm hard drive too, it will make a difference with accesses to the database that PokerTracker does, especially with 8Mb cache.
