• Answer:

  I assume these are different prices? For games, the i7 is overkill. No games can currently utilise hyperthreading, so you are paying more for something you cant use. Save your money and get a i5 2500 (Not the 2500k as the H67 motherboard cant use all its overclocking potential). Anything over 4-8GB is too much and games wont utilise it, so the first PC is again you are paying for something you realistically wont use. The 2nd PC has a 560Ti which is the better graphics card, so given all the above I would go with PC number 2 The list of games you give are quite varied. It will play the older games in that list fairly well ,but for some of the newer games like Rage you may have to drop the resolutions to get a stable and decent fps at the higher settings
