What would be a good gaming PC for me that could play these games without crashing/lagging?

My games include GTA 3, VC, and SA, Watch Dogs, Saints Row 3, Minecraft, Sims 2 (and all of the expansions packs), Farcry 3, and Mortal Kombat 9. So it's a big mix of old and new games.

Well if you want to run these games smoothly with no lag/crashes get yourself an i5 and a gtx 750 or 750 ti or even GTX 660 Boost. Make sure you get Windows 7 because 8 doesn't support older games that much. You'll be able to run all those games very nicely with good framerates
