Also I pretty much play games like Minecraft, GTA SA, M&B Warband etc... so, yeah...
Maybe one day I'll change the Graphics card.
See, these kinds of threads leave little information to help anyone give you good recommendations. Really you should be starting a thread in the Systems section of the forum, and using the form that can be found in the sticky to ask for proper advice. Information needed from you should include max budget, building the computer yourself, buying used, buying pre-built or finding one in the dumpster. What parts the budget needs to cover, things like keyboard, monitors, peripherals, etc. Nobody can really give you proper advice without input from you. Now, if you're dead set on those two ... to be blunt, crappy systems.. Well, I promise I'll go away for real this time, but.. I actually do know what I'm talking about, and so do some of the other people who have already posted in your thread.
